      Model 200EU Ultra-Sensitive NO/NO2/NOX Analyzer
    3. The gas analyzer Teledyne ML®9841B uses the low pressure chemiluminescent reaction between ozone and NO to measure the oxides of nitrogen with sensitivity down to ppb levels. When the NO molecule reacts with ozone it results in the formation of NO2 and the release of a photon. The ozone reactant is generated from an internal corona discharge source which has been highly refined to ensure longevity and stability. The ozone air source is dried with a permeation drier to stabilize the ozone output. The ozone and unknown gas sample are reacted in a heated reaction cell in front of a cooled photomultiplier tube (PMT). The PMT detector converts the photons that impinge on its surface to an electrical current which is processed and converted to concentration.
      The gas sample is alternately routed through a heated molybdenum converter which converts NO2 to NO for the NOx measurement, and directly into the reaction cell which produces the NO measurement. NO2 is computed as the difference of the two measurements. The two flow paths are carefully balanced to minimize artificial changes in NO2 which can result if the two measurements are not taken with respect to a common sample. Periodically, a sample with no NO is flowed into the reaction cell to establish a zero background. This ensures the outstanding zero stability of the analyzer.
      Optionally, the Teledyne ML®9841B can be equipped with an IZS (internal zero/span) check device which utilizes a constant temperature permeation tube to generate a known NO2 span gas concentration.

      To eliminate H2O interferences, the analyzer is equipped with a Nafion Dryer that dries the sample stream. In addition, the analyzer periodically monitors and corrects its baseline by routing the sample stream through a heated platinum scrubber. This helps to correct any instrument drift, ambient temperature related drift and eliminate any CO2 interferences. This function is known as Autoreference and can be performed under software control from once per hour to once per day as deemed necessary under the sampling conditions.
      Model 300EU Ultra-Sensitive Gas Filter Correlation CO Analyzer
    3. The gas analyzer Teledyne ML®9830B Carbon monoxide analyzer uses a combination of NDIR (non-dispersive infrared) and GFC (gas filter correlation) techniques. GFC minimizes the sensitivity to potentially interfering gases such as H2O and CO2. Infrared radiation is emitted from a long life electrically heated element and projected through a rotating filter wheel which is heated and contains one glass cell of CO and another filled with nitrogen. As the filter wheel rotates, a reference beam is detected when the cell with the CO is in the light beam, and a measurement of the unknown is detected when the cell with nitrogen is in the light beam. The CO filled cell is filled with such a concentration that it absorbs nearly all the energy at the wavelengths characteristic of CO. Both beams are directed through a heated multi-pass optical measurement cavity where the unknown gas absorbs the light in manner characteristic of the gases present. The light is further filtered to select the wavelengths of interest and sensed by a solid state detector. A ratiometric measurement processing scheme (measurement/reference) eliminates most sources of drift. These include, variations in source intensity, optical contamination of the measurement cell optics, variations in detector sensitivity, and alignment shifts--the effects of which are continuously corrected in the final measurement resulting in an extremely stable measurement of CO down to sub-ppm levels. The Teledyne ML®9830B is typically used with external calibration gases for automatic zero/span checks. High pressure span valves are available for using moderately pressurized gas sources.

    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.

    FID. GC technology used for complete separation of Methane, Ethlene oxide, Benzene, Styrene, BTX and many other compounds (application dependent).
    Organic compounds from the sample stream or separation column are injected into the detector housing where they are mixed with Hydrogen and air before entering the detector jet where the mixture is burned. During this process, organic compounds are broken down into carbon fragments and acquire a positive charge (i.e., become ionized) at the surface of the anode. Carbon fragments are detected by the collector. The signal is then amplified and sent to the data processing system.
    Temperature-controlled sampling system with GC column.
    Ranges: 0-10, 0-100, 0-1000 ppm THC. Other ranges available
    Model 4030 - Total Hydrocarbon Gas Analyzer
  • Gas Analyzers of Thermo Electron Corporation:
    Unlike instruments that use scrubbers or catalysts to measure only methane and total hydrocarbons, the Model 55C back-flushed gas chromatography system allows reliable measurements of NMHCs at sub-ppm concentrations of methane. In addition, the Model 55C's proprietary column design can achieve complete separation of methane from all C2 compounds, is unaffected by the oxygen recovery of low volatility compounds that other instruments may miss.

    Model 101E
  • Gas Analyzers of Thermo Electron Corporation:
    1. The gas analyzer 45C consists of an H2S to SO2 converter coupled to a pulsed fluorescence SO2 analyzer. Continuous H2S monitoring is accomplished by conversion of the H2S in the sample to SO2 and its subsequent detection by the SO2 analyzer according to the following reaction: H2S + 3/2(O2) › SO2 + H2O
      The converter section of the Model 45C cataytically converts each H2S molecule to SO2 so that the ouput of the SO2 analyzer is equal to the concentration of H2S entering the converter. Any SO2 present in the original sample is scrubbed prior to its entrace into the converter, providing an instrument response to H2S.

    Ammonia Converter, Model CNH3
  • 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.
    Ranges: 0-50 to 0-2,000 ppb, operator selectable; Dual ranges and auto-ranging supported
