The SRI Instruments (SRI) line of compact single- and dual-oven, portable gas chromatographs (GC) are economical laboratory instruments designed for on-site analysis of organic compounds. SRI GCs are equipped with temperature-programmable column ovens and electronic pressure control of all system gases. These GCs also include built-in, serially interfaced data acquisition hardware and software that permit use of IBM®-compatible desktop, notebook, and palmtop PCs. Windows-compatible software is also available in 16- and 32-bit versions. SRI GCs accept both packed and capillary columns and may be equipped with multiple injectors and detectors for series or independent operation. Purge-and-trap, thermal desorption, gas sampling, split-splitless, and liquid autosampling systems are available. SRI also manufacturers external detector units that may be connected by a heated transfer line to existing GCs.
The SRI GCs can monitor airborne emissions from hazardous waste sites and other emission sources before, during, and after remediation. They can also analyze soil, water, and gas samples for organic contaminants such as benzene, toluene, ethylbenzene, xylene, polychlorinated biphenyls, and pesticides. Their performance characteristics in the field have been proven by a large private, commercial, and government user base.
The SRI model 8610 GC was evaluated in January 1992 at a Superfund site under remediation. Results from this demonstration are presented in a peer-reviewed article entitled "Evaluation of Portable Gas Chromatographs" in the Proceedings of the 1993 U.S. EPA/Air and Waste Management Association International Symposium, VIP-33, Volume 2, 1993.
