Air Monitoring Monitoring of H2S, NH3, Benzene, Toluene, Ethylbenzene, Xylene and Dimethylethylamine
A new integrative cryogenic air sampler (patent application number 08/00669), able to overcome many of the limitations in current volatile organic compounds and methodologies odour sampling available from Labaqua (Spain). The sample is spontaneously collected in a universal way at 15 mL/min, selectively dried (reaching up to 95% of moisture removal) and stored under cryogenic conditions. The sample is Collected spontaneously in a universal way at 15 mL / min, selectively dried (Reaching up to 95% of moisture removal) and stored under cryogenic conditions.
The sampler performance was tested under time weighted average (TWA) conditions, sampling 100 L of air over 5 days for determination of NH3 , H2S, and benzene, toluene, ethylbenzene and xylenes (BTEX) in the ppm v range. The sampler performance Was tested under time weighted average (TWA) Conditions, sampling 100 L of air over five days for
determination of NH3, H2S, and benzene, toluene, Ethylbenzene and xylene (BTEX) in the ppm v range. Recovery was 100% (statistically) for all compounds, with a concentration factor of 5.5. Was Recovery 100% (Statistically) for all compounds, with a concentration factor of 5.5. Furthermore, an in-field evaluation was done by monitoring the TWA inmission levels of BTEX and
dimethylethylamine (ppb v range) in an urban area with the developed technology and comparing the results with those monitored with a commercial graphitised charcoal diffusive sampler. Furthermore, skilled an in-field evaluation Was done by monitoring the TWA inmission dimethylethylamine Levels of BTEX and (v ppb range) in an urban area with the Developer technology and Comparing the results with a commercial Those graphitised Monitor with diffusive charcoal sampler. The results obtained showed a good statistical agreement between the two techniques. The Obtained results show to good statistical agreement Between the two techniques.

SONIMIX 4001 Primary Standard Ozone Generator
The open path FTIR Air Monitoring System from Midac (USA) is compact, versatile, and rugged. Designed to detect, identify and measure a wide range of key contaminants sim - ultaneously, it has been used in many different configurations to address a diverse list of applications. Analysis is onsite through a continuous sampling path of up to 1000 meters.
Whether the application is battlefield chemical warfare agent analysis, civilian hazardous event response, industrial stack and/or fenceline monitoring, rocket plume analysis, analysis or environmental research (such as volcanic gas analysis), the MIDAC AM System can provide continuous, unattached, near real-time detection at ppb to % levels for hundreds of chemicals.
Each system includes a rugged, sealed 0.5cm-1 resolution inter - ferometer equipped with a choice of beamsplitters and detectors. The analyzer is coupled to a control PC via standard ribbon cable or long range fiber optic link. For extended sample paths, the FTIR can be mounted to a rugged, 10” Newtonian telescope with tripod. A high energy infrared source module on the opposite end of the sample path completes the system. Weighing approximately 40lbs. and measuring just 8” x 14” x 8” (WxDxH), the compact interferometer module is easy to transport and can be powered by a 12V car battery for complete freedom of movement. An optional lightweight sheet metal version of the FTIR is also available with a compact 3” telescope.
