Title:Monitoring and identification of hazardous air pollutants by fast capillary gas chromatography with PID/FID detection
Abstract Body:First passed in 1970, the Clean Air Act (CAA) intended to regulate air emissions from both mobile and stationary sources, The 1990 Clean Air Act Amendment (CAAA) involved a new approach: regulation by industry rather than by chemical; re-focusing the program to one which is technology and performance based. The US Congress generated a list of 189 hazardous air pollutants (HAP's) as a focused guideline to reducing emissions of HAP's from major sources of air pollution (1).
Driscoll et al (2) described a method for the identification of hydrocarbons using gas chromatography to separate and the ratio of the photoionization detector (PID) and flame ionization detector for identification. The FID provides the same response for Hexane, hexane and benzene. The PID response is related to the number double bonds (p electrons) so the PID /FID ratio is 10 for hexane, 20 for hexane and 60 for benzene, so we can used this ratio along with the retention time on a 30 meter capillary for positive identification of particular components. This method, of a single column and PID/FID ratios for identification has been employed in EPA and many state agencies methods instead of using two different columns for identification.
We used a new miniature PID/FID in-series tandem design along with a 30M x 0.32 mm & 5m film column that provides with temperature programming for the analyses. This column will allow us to separate the light hydrocarbons along the SVOC's. We will be using the restistively VICI capillary columns that, because of their low mass, provide rapid heating and cooling of the column.

Gas ChromatographyApplication:EnvironmentalPrimary Focus:ApplicationTitle:A Portable GC/PID for the Analysis of Odorous Sulfur Compounds in Ambient AirKeywords:Air GC Industrial Hygiene Portable Instruments A capillary column gas chromatography method was used for the analysis of sulfur compounds such as hydrogen sulfide, methyl mercaptan, dimethyl sulfide, and dimethyl disulfide in ambient air. The concentration of these sulfur compounds is typically very low (low to sub ppb) in ambient air. Their odor threshold is at the low ppb levels so it is also necessary to make field measurements near odorous sulfur sources such as refineries, pulp and paper mills, etc. because of the hi…
