Report Date : JAN 1973 Pagination or Media Count : 23 Abstract : A preliminary evaluation of techniques of sampling and gas chromatographic analysis for low levels of sulfur hexafluoride was conducted to determine the most feasible method for available equipment. Using a Tracor MT-150 gas chromatograph equipped with Nickel 63 electron capture detector and polarized dc voltable, it was possible to detect sulfur hexafluoride at a concentration of 0.06 ppb with a 5A molecular sieve column and nitrogen carrier gas, without preconcentration of the sample. Also, a comparison of glass and Saran sampling materials proved that no detectable loss of the tracer gas resulted with the Saran bags (between 6 ppm and 0.06 ppb SF6
Measurement solution for accurate continuous formaldehyde measurement formaldehyde in emissions and ambient air applications
by Protea Limited based in Middlewich, UNITED KINGDOMFormaldehyde (HCHO) is the simplest aldehyde species and is present, or generated by, many sources (both natural and industrial). It is classed as a substance that is toxic and harmful to human health.
Air monitoring equipments for workplace and personal exposure monitoring
by Gradko International Ltd based in Winchester, UNITED KINGDOMMany occupations involve the use of hazardous substances or processes, where pollutants may be ingested, inhaled or absorbed through the skin. General ambient pollutants can also have health implications in otherwise non-hazardous workplaces. Occupational exposure limits regulate many pollutants based on an eight-hour working day. Personal exposure assessments can be made over an eight-hour period (Time Weighted Average (TWA) exposure) using our simple to use monitoring equipment.
