MULTISPECTRAL DETECTION FOR GAS-CHROMATOGRAPHY

Over the past several years, capillary gas chromatography (GC) with Fourier transform infrared (FT-IR) and/or mass spectral (MS) detection has become the primary analytical tool for qualitative and quantitative analysis of complex mixtures. Because of the wide range of applications, the analytical requirements have motivated several recent chromatographic and detection developments. This review examines those, illustrating with applications that demonstrate the power of GC and multidimensional GC-MS, GC-FT-IR and GC-FT-IR-MS systems for solving a wide variety of analytical problems. Additionally, the article discusses the integrated performance of such analytical systems with the aid of recent sample introduction and computer data analysis technique advances.
