New portable micro gas chromatograph for environmental analysis
- Louisiana State Univ., Baton Rouge, LA (United States). Inst. for Environmental Studies
Efforts directed at developing a truly portable method for the analysis of semivolatile compounds have led to the construction and testing of a new generation of micro-GC instrumentation. Building on the successful application of microbore GC columns for in-field analysis of volatile organic compounds, the instrument development group at the LSU-Institute for Environmental Studies has developed a hand portable GC capable of analyzing samples containing compounds with retention indices (100% dimethylpolysiloxane column) up to at least 2,000 in less than 4 minutes, using less than 50 watts (peak) of electrical power. In addition to the ability to analyze semivolatile compounds, the chromatograph is capable of analyzing volatile organics competitively with the most sophisticated of the current commercial portable GCs. The presentation will evaluate chromatographic performance of the instrument at its latest stage of development and demonstrate some applications to environmental analysis using the prototype instrument.
