Chemometrics in Chromatography

چکیده

Figure 1 Classification of chromatograms are based on the relative abundance of all the peaks in the mixture. Chromatography is an extremely versatile technique for the analytical laboratory. The chromatographic patterns generated by modern instruments are used in a wide variety of quantitative and qualitative analyses. The techniques are robust enough (and we have assembled experience enough) to allow a rapid development of chromatographic methods and move this experience into routine use in an analytical laboratory, quality control laboratory, or even an in-line process setting.
