Chapter 2 Separation, clean-up and recoveries of persistent trace organic contaminants from soils, sediment and biological matrices

摘要: Publisher Summary New methodologies and validation programs are continually required for identifying organic compounds as environmental contaminants. This chapter discusses the analysis of development analytical techniques that focuses on (i) fitness purpose (ii) cost-effective chemical methodology data evaluation. The also presents protocol sample treatment storage, both in field laboratory, because once is obtained, it essential to maintain quality material so final information representative concentrations determinant original sample, such biological tissue. A specific problem related automation contaminant effect nonvolatile co-extracted performance gas chromatography (GC), when injected high-resolution column. Gel-permeation (GPC) ideally suited this separation basis molecular size can be used provide an automated preparation where volatile requires isolating prior GC analysis.
