A sample conditioning system providing a constant clean and dry sample to analyzers/GCs/detectors for continuous analysis. Provides ultra-pure and ideal gas phase sample to gas chromatographs/analyzers for radically reduced maintenance. Separates volatile hydrocarbons from liquid samples such as water, crude oil, diesel, or steam/condensate for analysis in the gas phase by a detector/GC. No moving parts reduces down-time. Ability to concentrate or dilute sample. Maintains a representative sample.

The ability to analytically quantify and measure oil in water is greatly enhanced with the Sample Transfer Stripper (exclusive ASI Membrane Technologies) and the solid state sensor offered by Analytical Systems Keco. Our oil in water analyzer (also called an oil in water monitor) is very easy to maintain and does not require routine calibrations in the field. It is field-proven to maintain a typical 99% up-time. The Model 204 analyzer accurately measures total hydrocarbons including aliphatic and aromatic hydrocarbons. Alternative oil in water monitors utilizing the UV Fluorescence methods do not have the ability to measure aliphatic compounds. Furthermore, the UV Fluorescence method suffers from cross-sensitivity with components in the water not intended to be measured, such as debris and contamination. This gives false high readings and false high alarms. The on-line analysis offered by the Model 204 is economically superior to inaccurate laboratory analyzers where unstable grab samples result in oil deterioration that produce analytical errors.

Hydrocarbon VOC in water analyzer | The ability to analytically quantify total hydrocarbons and volatile organic compounds (VOCs) in cooling towers, heat exchangers, holding ponds, produced water, run-off water, and waste water is greatly enhanced with the Model 204 due to the Sample Transfer Stripper, utilizing exclusive ASI Membrane Technologies, and the tin oxide sensor technology offered by Analytical Systems Keco. The VOC in water analyzer system utilizes patented and exclusive features only available from Analytical Systems Keco. The analyzer measures aliphatic and aromatic hydrocarbons (including important carcinogenic compounds BTEX like benzene, toluene, and xylene)

H2S in Water Analyzer: The ability to analytically quantify H2S in Water online is enhanced with the Sample Transfer Stripper™ (exclusive ASI Membrane Technologies) and the advanced electrochemical H2S sensor or rateometric-colorimetric H2S detector technologies offered by Analytical Systems Keco. Economic payout is increased because of this automated and continuous process monitor. The most effective process for measuring H2S in water involves representatively stripping the H2S vapor from the water for precise measurement in the gas phase.

H2S in Liquids Analyzer: The ability to analytically quantify H2S in liquid phase such as naphtha, water, crude oil (light, medium and heavy), condensate and gasoline is enhanced with the Sample Transfer Stripper, exclusive ASI Membrane Technology and rateometric-colorimetric detection technology offered by Analytical Systems Keco (ASI).

The ability to analytically quantify H2S in fuel oil is enhanced with the Sample Transfer Stripper utilizing exclusive ASI Membrane Technologies and rateometric-colorimetric technologies offered by Analytical Systems Keco. The principle of operation requires a continuous free flowing liquid sample into a heater where the Sample Transfer Stripper (STS) unit separates the liquids (fuel oil) from the H2S gas sample. An H2S free air or nitrogen carrier then sweeps the H2S gas sample to the H2S detector for quantitative analysis in ppbw, ppmw, and up to saturation. A liquid validation by PermTubeTM is optional. The detection technology is based on chemically specific density changes. The lead acetate sensing tape utilized in our analyzers is the only detection method that is absolutely specific to H2S. Optical illumination & detection are integrated for maximum resolution accuracy. Economic payout is increased because of this automated continuous process analyzer.

H2S in Diesel Process Analyzer: The ability to analytically quantify H2S (hydrogen sulfide) in non-volatile liquids, such as naphtha, water, crude oil (light, medium & heavy), and gasoline, are enhanced with the Sample Transfer Stripper S.T.S. (Exclusive Membrane Technology) and ASTM approved radiometric colorimetric technology methods offered by Analytical Systems International.

With our H2S in crude oil analyzer, the ability to analytically quantify H2S in light, medium & heavy crude oil and condensate is greatly enhanced with the Sample Transfer Stripper (STS) utilizing exclusive ASI Membrane Technologies and rateometric-colorimetric detection technology. This principle of operation is described in various ASTM methods including D4084-82, D4468-85, and D4045-81.

H2S in Condensate Analyzer: The ability to analytically quantify hydrogen sulfide in condensate is enhanced with the Sample Transfer Stripper, exclusive ASI Membrane Technology and ratiometric colorimetric technologies offered by Analytical Systems International (ASI). This principle of operation is described in various ASTM methods including D4084-82, D4468-85, and D4045-81. The process of measuring hydrogen sulfide in condensate samples is to representatively separate the hydrogen sulfide from the condensate for measurement in the gas phase. The problematic and complicated ‘Headspace’ system, which often suffers from liquid carry-over, is not required for this separation. ASI utilizes the state-of-the-art Sample Transfer Stripper (STS) with exclusive ASI Membrane Technology to efficiently and reliably separate the H2S from the liquid sample. The STS is an extremely simple device that provides an ultra-clean and dry sample to the detector for analysis. The STS uses 90% fewer parts than the complicated ‘Headspace’ method. This results in radically reduced maintenance requirements when compared to the headspace method and also enhances analytical reliability. ASI is established as the world-wide leader in H2S in Condensate analysis due to the many benefits of this exclusive technology.

Analytical Systems KECO was established in 1984 employing staff with over 40 years of analytical experience providing field proven process and laboratory analyzers to the gas processing, pipeline, refining, chemical, and water processing industries worldwide. Many ASTM methods, patents, and exclusive features are utilized with our analyzers.
