Chapter 10 Spectroscopy And Chromatography

Abstract

Analytical instrumentation is one the important techniques to analyse the pollutants in environmental samples. This chapter describes various types of instrumentation that are extensively applied for the analysis of pollutants in environmental samples. Spectroscopy is one of the most important and powerful analytical tools for the useful analysis of target compounds in complex environmental samples. There are various forms of technique depending on the detection system and the features of the analyte to be analysed, thus enabling different application fields [1]. Atomic absorption spectroscopy (AAS), Ultraviolet-visible (UV-Vis) spectroscopy, infrared spectroscopy (IR) and inductively coupled plasma-mass spectroscopy (ICP-MS) are the common spectroscopic technique used in environmental analysis. Chromatography is an important and powerful analytical tool for the effective separation and purification of target compounds in complex environmental samples. Chromatographic techniques, such as gas chromatography (GC) and high-performance liquid chromatography (HPLC) are commonly used for the sensitive analysis of pollutants in environmental samples.
