THC (total hydrocarbons)
  • Gas Analyzers of ANTEK:
    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.

NH3
  • Gas Analyzers of California Analytical Instruments:
    The CAI gas analyzer 701 system consists of an Innova Airtech Model 1312 (1314) Photoacoustic Infrared and a CAI Model 101 Heated sample diluter. The Model 1312 (1314) is an Infrared analyzer with a photoacoustic detector. The analyzer has a dynamic range from 0.07 to 20,000 ppm for ammonia before dilution. Samples containing moisture greater than 1% are appropriately diluted in the 101 heated diluter; and with this analyzer/diluter combination, it is possible to monitor ammonia samples with humidity in excess of 40%. The raw stack sample is drawn by the 101 diluter via heat traced sample lines and a heated internal pump. The appropriately diluted sample is then presented to the 1312 (1314) analyzer for direct analysis.
    A critical requirement in the ammonia determination is the transportation of the sample to the analyzer without any losses. Generally, some kind of sample conditioning equipment is used. However, all these processes can result in indeterminate sample losses. As in any extractive technique it is best to transport the sample with heat traced sample lines. Dilution at the stack does not prevent sample losses.
    The minimum detection limit prior to dilution is 0.07 ppm. The actual minimum detection limit within a sample after dilution depends upon the dilution ratio but is typically down to 0.3 ppm with a 1:5 dilution. This configuration allows the direct analysis of ammonia in samples containing high levels of CO2 and moisture, commonly present in any combustion process. The interference of CO2 in the traditional NDIR ammonia measurements is eliminated by dilution and the cross compensation feature available within the 1312 (1314).

    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.

    Operating Principle: A flanged probe is mounted at the stack. It is connected to the analyzer unit with a sample line that is heated to approx. 20-40 °C. The sample gas is drawn into the dilution unit by an ejector pump, passing a heated (500 °C) ceramic filter. A critical orifice stabilizes the sample flow; a sensor continuously controls the suction vacuum. The sample filter is cleaned automatically. A part of the diluted sample is passed through the heated catalyst where the different forms of mercury of the sample are converted into the elemental form. The thus treated sample is transported through slightly heated PFA tubing into the Mercury Atomic Absorption Detector. This detector uses a pre concentration technique with the Mercury Gold Trap, thus revealing one of the most sensitive mercury detectors in the market.
    A Glass lined self heating Low flow probe minimizes salts plugging in wet applications The dual function reactor/converter converts all forms of mercury into elemental and also binds interfering components like SO2 and HCl.
