SO2
  • Gas Analyzers of Teledyne Monitor Labs:
    Ranges (Min/Max): 0-10 ppm / 0-5000 ppm
    Model 100EH
  • Gas Analyzers of Thermo Electron Corporation:
    1. Pulsed fluorescence technology.
      The pulsing of the U.V. source lamp serves to increase the optical intensity whereby a greater U.V. energy throughput and lower detectable SO2 concentration are realized. Reflective bandpass filters, as compared to commonly used transmission filters, are less subject to photochemical degradation and more selective in wavelength isolation. This results in both increased detection specificity and long term stability.
      Preset Ranges: 0-0.05, 0.1, 0.2, 0.5, 1, 2, 5, and 10 ppm; 0-0.2, 0.5, 1, 2, 5, 10, 20, and 25 mg/m3

      Model 450C Pulsed Fluorescence Analyzer (H2S and SO2)

NOx
  • Gas Analyzers of California Analytical Instruments:
    1. Principle of chemiluminescence for analyzing the NO or NOx concentration within a gaseous sample. In the NO mode, the method is based upon the chemiluminescent reaction between ozone and nitric oxide (NO) yielding nitrogen dioxide (NO2) and oxygen. This reaction produces light which has intensity proportional to the mass flow rate of NO2 into the reaction chamber. The light is measured by means of a photodiode and associated amplification electronics. In the NOx mode, NO plus NO2 is determined as above, however, the sample is first routed through the internal NO2 to NO converter which converts the NO2 in the sample to NO. The resultant reaction is then directly proportional to the total concentration of NOx. Sample enters the analyzer directly into a heated chamber and is maintained at an elevated temperature. The moisture will remain in the vapor state, thus ensuring no loss of the NO2.
      Auto Calibration.
      Ranges: 0-1 to 3,000 ppm NO or NOx (Four user programmable ranges) (Higher Ranges Available upon Request)
      Model 600 CLD - No/Nox Analyzer

      Oxygen RANGE 0 – 25%
      Model 650 NOxygen - No/Nox Analyzer
    3. The chemiluminescence principle for analyzing the NO or NOx concentration in a gaseous sample. In the NO mode, the chemiluminescence reaction between ozone and nitric oxide (NO) yields excited nitrogen dioxide (NO2* ) and oxygen. Approximately 10% of the NO2* produced from this reaction is in an electronically excited state. The transition from this state to a normal state produces light intensity proportional to the mass flow rate of NO2 into the temperature controlled reaction chamber. The light is measured with a photodiode and associated amplification electronics. In the NOx mode, NO plus NO2 is determined. The sample is first routed through the internal converter which converts the NO2 in the sample to NO. The converter is preconditioned vitreous carbon; operating at relatively low temperatures of 130-200°C. Has an operating life of 106 ppm hours or one year. NO2 concentrations can be converted in the entire range of the analyzer.

    Analysis Method: Flame Ionization Detector (FID).
    The analyzer contains a burner in which a small flame is sustained by regulated flows of air and either pure hydrogen or an FID gas (40/60 mixture of hydrogen and helium or hydrogen and nitrogen) as fuel gas. A burner jet, used as an electrode, is connected to the negative side of a precision power supply. A “collector” electrode is connected to a high impedance, low noise electronic amplifier.
    When a gas sample is introduced into the burner, it is ionized in the flame creating a current flow from burner tip to “collector” proportional to the amount of THC in the sample. This current flow is measured and amplified to present a linear signal output proportional to the amount of THC present. This output presents THC as methane.

The HFID analyzer has a heated oven (191°C) which contains a burner and an optional heated pump. The small flame of the burner is elevated and sustained by regulated flows of air and either pure hydrogen or a 40/60 mixture of hydrogen and (helium or nitrogen). The split ring detector contains 2 electrodes. One electrode is negatively polarized using a precision power supply and the other electrode, known as the "collector" is connected to a high impedance, low noise electronic amplifier. The two electrodes establish an electrostatic field. When gaseous sample is introduced to the burner, it is ionized in the flame and the electrostatic field causes a small current bewteen the electrodes. This current is measured by the precision electrometer amplifier and is directly proportional to the hydrocarbon concentration of the sample.

    2. The Flame Ionization Detection (FID) method to determine the total hydrocarbon concentration within a gaseous sample. The analyzer contains a burner in which a small flame is elevated and sustained by regulated flows of air and either pure hydrogen or a 40/60 mixture of hydrogen and helium or hydrogen and nitrogen. The burner jet is used as an electrode and is connected to the negative side of a precision power supply. An additional electrode, known as the “collector,” is connected to a high impedance, low noise electronic amplifier. When a gaseous sample is introduced to the burner, it is ionized in the flame and the electrostatic field causes the charged particles (ions) to migrate to their respective electrodes. The migration creates a small current between the electrodes. This current is measured by the precision electro-meter amplifier and is directly proportional to the hydrocarbon concentration of the sample.

    FIA-510 Total Hydrocarbon Analyzer
  • Gas Analyzers of Siemens:
    The measuring principle:
    The heart of the FIDAMAT 6 is the flame ionization detector. The sample gas is mixed with Hydrogen and a certain amount of air and fed to nozzle in the combustion chamber. There the mixture is ignited and the hydrocarbons are burnt, i.e. ionized. An electrode on top of the flame picks up the ions. The ionization current is proportional to the amount of Hydrocarbon atoms in the sample gas. Extremely important with this measurement is the optimized and stable adjustment of all pressures and flows. This is perfectly achieved in the FIDAMAT 6 by high-quality pressure regulators and capillaries.

  • Gas Analyzers of Sick|Maihak:
    The H2S gas analyzer MONOCOLOR operates semi-continuously by the colorimetric measurement principle. H2S is measured with a dry reaction on a test paper strip which is saturated with a chemically selective color indicator (lead acetate or silver nitrate) The intensity of the test paper strip is proportional to the mean concentration and to the fl owrate and will be determined by comparison between gased or not gased test paper strip. This measuring principle is very selective, even in case of different sulfur compounds in the sample gas and allows the measurement of smallest H2S concentrations.

NH3
  • Gas Analyzers of Teledyne Monitor Labs:
    The gas analyzer 201E NH3 analyzer measures ambient ammonia using the chemiluminescence principle and an APIdesigned external ammonia converter and sampling system.
    Ammonia is difficult to measure accurately because of a tendency to be absorbed into other materials. The “stickiness” of the gas results in slow response times and inaccurate concentration values. The Model 201E has been designed to overcome the problems of ammonia gas analysis through increased flow, minimum surface area and selected construction materials.
    In operation, sample gas is passed through the M501NH converter, which converts NH3 and other compounds to NO, producing the total oxides of nitrogen (TNX). In the next cycle the sample is routed through a molybdenum converter which converts nitrogen oxides (less NH3) to NO, producing the Tn reading. The difference between these readings (TNX – TN = NH3) provides a reading proportional to the NH3 concentration.
    Continuous self checking with warning alarms, external converter, minimal surface area in contact with sample, low absorption wetted parts, heated sample manifold, adaptive filtering optimizes response time, temperature & pressure compensation, internal data logging with 1 min to 24 hour averages.

    The over many years proven ZrO2 technology offers exact measurements in accordance with the current sensor measuring principle. This means that a linear sensor signal is achieved over the total measuring range with a fixed physical zero point.
    The O2 probe contains a ZrO2 solid electrolyte tube closed on one side. A constant measured gas flow passes through the heated solid electrolytical cell. A DC voltage is applied to the cell electrodes at . 650 °C to determine the O2 concentration. The O2 ion current in the electrolytes is then measured. This is derived from the linear correlation betw. O2 conc. and gas quantity passing through the cell per time constant.

  • Gas Analyzers of California Analytical Instruments:
    1. METHOD OF OPERATION - NDIR. The infrared absorption characteristics of gases. Using a single infrared beam to measure gas concentrations, this analyzer produces highly stable and reliable results. A single infrared light beam is modulated by a chopper system and passed through a sample cell of predetermined length containing the gas sample to be analyzed. As the beam passes through the cell, the sample gas absorbs some of its energy. The attenuated beam (transmittance) emerges from the cell and is introduced to the front chamber of a two-chamber infrared microflow detector. The detector is filled with the gas component of interest and consequently the beam experiences further energy absorption. This absorption process increases the pressure in both of the chambers. The differential pressure between the front and rear chambers of the detector causes a slight gas flow between the two chambers. This flow is detected by a mass-flow sensor and is converted into an output signal. METHOD OF OPERATION - OXYGEN. The oxygen analyzer section utilizes the paramagnetic method to determine the percent level of oxygen contained in the sample gas. The oxygen level is displayed on the LCD panel in engineering units.
      Measures from 0-50 ppm up to 100% Full Scale (CO / CO2 / CH4 / C3H8 / SO2)

    4. The heart of the CAI Infrared Gas Analyzer Series is the unique optical bench. The single beam design requires no optical alignment. Sample cells have replaceable gold foil liners should sample contamination ever occur. The microflow detector provides greater detectability, greater stability and a lower sensitivity to vibration than conventional analyzers utilizing solid state or condenser microphone detectors. Couple this optical bench to the electronics and compact case design and you have an analyzer.
      CAI offers two oxygen analyzer options for the 100, 200, 300 series:
      Galvanic fuel cell and paramagnetic sensor.
      Either option or both can be selected for the series. Both read directly in digital percent oxygen. Both have multiple ranges and multiple linear outputs. They may be configured as a stand-aloneanalyzerseries 100 orteamed with an NDIR bench in the series 200 or 300 to deliver a multicomponent solution to your gas analysis requirements.
      METHOD OF OPERATION: Non Dispersive Infrared (NDIR). NDIR analyzer section is based on the infrared absorption characteristics of gases. A single infrared light beam is modulated by a chopper system and passed through a sample cell of predetermined length containing the gas sample to be analyzed. As the beam passes through the cell, the sample gas absorbs some of its energy. The attentuated bean (transmittance) emerges from the cell and is introduced to the front chamber of a two-chamber infrared microflow detector. The detector is filled with the gas component of interest and, consequently, the beam experiences further energy absorption. This absorption process increases the pressure in both chambers. The differential pressure between the front and rear chambers of the detector causes a slight gas flow between the two chambers. This flow is detected by a mass-flow sensor and is converted into an AC signal. The AC signal is amplified and rectified into a DC voltage signal and ultimately supplied to the output terminal and digital panel meter. The electrical output signal is directly proportional to the concentration of the sample gas.
      Oxygen- Galvanic Fuel Cell. The CAI oxygen analyzer utilizes a low cost fuel cell to determine the percent level of oxygen contained in the sample gas.
      Oxygen-Paramagnetic. The CAI oxygen analyzer measures the paramagnetic susceptibility of the sample gas by means of a magneto-dynamic type measuring cell.
      The CAI measuring cell consists of a dumbbell of diamagnetic material, which is temperature controlled electronically at 50°C.
      The higher the oxygen concentration, the greater the dumbbell is deflected from its rest position. This deflection is detected by an optical system connected to an amplifier. Surrounding the dumbbell is a coil of wire. A current is passed through this coil to return the dumbbell to its original position. The current applied is linearly proportional to the percent oxygen concentration in the sample gas.

    5. NDIR PRINCIPLE OF OPERATION. The analyzer uses a technique based on the infrared absorption characteristics of gases to measure gas concentration. Use of an efficient single beam design results in a good long-term stability. A single beam of infrared energy is modulated and passed through a sample cell containing the gas to be measured. The beam emerges attenuated by the amount of energy absorbed by the gas(es) in the sample. Changes in the concentration of the gas(es) result in changes in the intensity of the beam. The remaining energy in the beam is passed serially through two cavities of an infrared detector, a mass-flow sensor filled with gas of the type to be measured. Changes in the intensity of the beam change the pressure differential between the cavities and consequently the balance of the electrical bridge in the detector circuit.
      O2 PRINCIPLE OF OPERATION. The Model 10/20/30 is designed to measure percent levels of oxygen. The analyzer uses a galvanic fuel cell, which is an electrochemical transducer. The fuel cell contains a cathode, anode and an electrolyte. A permeable membrane holds the electrolyte in the cell. The sample flows over the membrane and oxygen diffuses into the fuel cell where it reacts with the electrolyte. This reaction produces an electrical current which is directly proportional to the concentration of oxygen in the gaseous mixture surrounding the cell. The current output is linear with an absolute zero. In the absence of oxygen the fuel cell produces no current.

  • Gas Analyzers of Land Instruments International:
    1. The FGAII continuous emissions monitor uses Advanced Dual Sensor Technology (ADST) to measure specific flue gas components. The main advantage to this technology is the automatic zero drift correction the analyzer performs every 30 minutes. In addition, ADST performs a measurement verification during the drift correction cycle.
      The accuracy and reliability of the FGAII in the measurement of SO2 begins with the sample conditioning system. A two-stage cooler and acid resistant sample path inside the ChillerProbe™, ensure there is no significant loss during gas transportation. High accuracy sensors inside the analyzer.
      FGAII is designed for very low level NOx measurement, now obligatory in some countries. Importantly, the analyser measures both NO and NO2 separately, these are combined to give a true NOx measurement output. E.g. very useful information for SCR operation on IC engines The inherent problems with catalytic NO2 convertors are therefore completely avoided.
      The analyzer system is built from functional modules rather than separate analysers. It can be expanded where future requirements necessitate additional gases or functionality.
      FGAII can be supplied with manual or fully automatic calibration. Microprocessor-driven routines can direct the test gas through the entire probe and sample system; or a simple analyzer check can be made. The time interval and sequence of automatic calibration is fully user configurable to meet the requirements set by local environmental authorities.
      Manual Calibration, automatic Calibration (option), with empty bottle detection, automatic Cross-interference correction, 3-point linearity check, calibration using Certified or Protocol gases.

    2. FGA 900 Series stack gas emissions gas analyzers can measure up to 3 gases in a single instrument.
      FGA is an extractive sampling multi-gas analyzer system. The flue gas is extracted using a sample probe. The gas is then transported via a sample line, to the cooler unit fitted inside the analyzer, where the moisture is removed. The dry and cooled sample gas is then filtered to remove particulates before being directed into the measurement system. The measurement system is made up of pairs of sensors. Each sensor is fed alternately with sample gas and air. The sensors generate an electrical output in proportion to a specific gas component.
      Fully integrated system in a single compact box - no additional components required
      True measured Total NOx - separate NO + NO2 sensors for true NOx monitoring, no converters necessary
