Air/Gas Quality Testing

labfilter-02-copy

TRI uses a gas chromatograph (GC) as the most appropriate method for the analysis of gaseous breathing air components. In a GC, the components of the air sample are carried through an analytical column by an inert gas (the carrier gas). The sample mixture is partitioned between the moving carrier gas and a solid support and/or stationary phase. The solid support stationary phase selectively retards the sample components according to their distribution coefficient until they form separate bands in the carrier gas.

These component bands leave the column in the gas stream and are sensed by the appropriate detector. The resulting analog signal is input to an integrator, recorded on an electronic data file, and printed by the attached printer, creating a physical copy as well as an electronic file. The integrator records the retention times of the peaks (which identify the components) and area under the peak (which corresponds to the amount present).

All instrumentation calibration is performed per ISO/IEC 17025 and ANSI/ISO/ASQ 9001-2000. The instrumentation used in processing gas samples goes through a rigorous process of checks and re-checks. Currently, this equipment includes a SRI Gas Chromatograph Model 8610A, identification number 70-09.
