Fast Gas Chromatography and Its Use in Pesticide Residues Analysis

Abstract

Classification according to the GC speeding-up strategies is mentioned and the main part of the chapter is devoted to the fast GC in the analysis of pesticide residues with the use of narrow-bore columns (internal diameter I.D. <0.2 mm). Specificity of pesticide residues analysis as well as problems associated with analysis of pesticides in general are discussed. Sample preparation mainly from the point of view of time requirements and feasibility for fast GC is briefly outlined. Special attention to the selectivity enhancement by the negative chemical ionization approach is devoted. Applicability of fast GC for pesticide residues in real-life samples is demonstrated
