Direct-linked gas chromatography-Fourier transform infrared-mass spectrometer system

Linked Gas Chromatography Infrared Mass Spectrometry

“…If expensive high-performance IR and mass spectrometers are required for success, it is not likely that the method will be widely adopted for routine mixture analysis. For example, a review that appeared late in 1982 (20) discussed GC/IR/MS analysis studies using very expensive high-performance double focusing (12) and Fourier transform mass spectrometers (19) in combination with top-of-the-line FT-IR spectrometers. Such systems involved use of close to half a million dollars' worth of equipment.…”

“…In our laboratory (12,19), searches of computer-readable mass spectral and gas-phase IR spectral libraries were used for identification of mixture components. To accomplish specific identification, the same component was required to appear 574 A · ANALYTICAL CHEMISTRY, VOL.…”

“…If finding the right information on the latest patents, products and markets in tern was in 1980, as described in a paper published early in 1981 (12).…”

“…Prior to the first demonstration of GC/IR/MS (12), there were numerous reports of various instrument systems exploiting complementary information for organic analysis. In one of the earliest papers, Uden and co-workers described a pyrolysis GC system in which samples were trapped and subjected to subsequent MS, elemental analysis, and GC/IR measurement, although the instruments were not linked (13).…”
