| Abstract |
The purpose of this contract was to develop instrumentation for the collection and analysis of atmospheric acetylene at the part per billion level. The reason for measuring acetylene is that it comes primarily from vehicular exhausts and thus can be used as a tracer of pollution from urban to rural areas. The approach used was an automated concentration technique whereby one liter of air was collected in a 1-1/2 x 1/8 inch tube filled with molecular sieve. The trapped contents were then automatically flushed into a gas chromatograph for separation and assay of acetylene. This collection and analysis system was designed to automatically perform three acetylene analysis per hour at acetylene concentrations ranging from .03 to 250 PPB. A portable collection device, in addition to the automated collection and analysis instrumentation, was also developed for the collection of acetylene in locations far removed from the analyzer. The collection devices used in the portable sampler were identical to the collection device on the gas chromatograph. |
