MULTISPECTRAL DETECTION FOR GAS-CHROMATOGRAPHY

Over the past several years, capillary gas chromatography (GC) with Fo urier transform infrared (FT-IR) and/or mass spectral (MS) detection h as become the primary analytical tool for qualitative and quantitative analysis of complex mixtures. Because of the wide range of applicatio ns, the analytical requirements have motivated several recent chromato graphic and detection developments. This review examines those, illust rating with applications that demonstrate the power of GC and multidim ensional GC-MS, GC-FT-IR and GC-FT-IR-MS systems for solving a wide va riety of analytical problems. Additionally, the article discusses the integrated performance of such analytical systems with the aid of rece nt sample introduction and computer data analysis technique advances.
