Monitoring emissions from industry. Gases released into the atmosphere from industrial processes (stack or flue gases) may contain many different pollutants. Calibrate continuous emission monitoring (CEM) systems. Provide data for environmental impact assessments.
AGS is helping various industries to cut down the air pollutions and trying to control the air pollutions in every possible manner. We are providing services to create a pollutions free environment and at the same time we are also manufacturing the necessary machinery for the same.

Monitoring activities at a chemical manufacturing site.
Air sampling should be conducted using a variety of media to identify the major classes of airborne contaminants and their concentrations. The following sampling pattern can be used as a guideline. First, after visually identifying the sources of possible generation, collect air samples downwind from the designated source along the axis of the wind direction. Work upwind, until reaching or getting as close as possible to the source. Level B protection should be worn during this initial sampling. Levels of protection for subsequent sampling should be based upon the results obtained and the potential for an unexpected release of chemicals.
After reaching the source, or finding the highest concentration, sample cross-axis of the wind direction to determine the degree of dispersion. Smoke plumes, or plumes of instrument detectable airborne substances, may be released as an aid in this assessment. To ensure that there is no background interference and that the detected substance(s) are originating at the identified source, also collect air samples upwind of the source.
Perimeter Monitoring
Fixed-location monitoring at the "fenceline" or perimeter, where personal protective equipment is no longer required, measures contaminant migration away from the site and enables the Site Safety Officer to evaluate the integrity of the site's clean areas. Since the fixed-location samples may reflect exposures either upwind or downwind from the site, wind speed and direction data are needed to interpret the sample results.
Periodic Monitoring
Site conditions and thus atmospheric chemical conditions may change following the initial characterization. For this reason, monitoring should be repeated periodically, especially when:
Work begins on a different portion of the site.
Different contaminants are being handled.
A markedly different type of operation is initiated (e.g., barrel opening as opposed to exploratory well drilling).
Workers are handling leaking drums or working in areas with obvious liquid contamination (e.g., a spill or lagoon).
