Until recently, the application of liquid chromatography (LC) in pesticide analysis was usually focused on groups of compounds or single compounds for which no suitable conditions were available for analysis with gas chromatography (GC). However, rec

Method validation is a key element in both the elaboration of reference methods and the assessment of a laboratory's competence in producing reliable analytical data. Hence, the scope of the term method validation is wide, especially if one bears in

In a previous work, coupled-column LC (LC/LC) with direct large-volume sample injection for the analysis of β 2 -agonists in bovine urine was investigated, in view of its combination with thermospray (TSP) tandem mass spectrometric (MS/MS) detection

Deactivation of precolumns with an ultra thin film of OV-1701 provided inertness at least equal to silylation, but better resistance to water. Dynamic coating of the raw fused silica capillary is, furthermore, much faster than the hydrothermal treatm

The determination of pesticides in water is often based on liquid-liquid extractions combined with concentration by evaporating the organic solvent followed by analysis with capillary GC. The use of selective detection such as thermionic detection (N

An overview is given of the applicability of coupled chromatographic systems in pesticide residue analysis. These systems can be based on liquid chromatography (LC) coupled to itself (LC-LC) or to gas chromatography (LC-GC) and obviously GC can also

The ASPEC (Automatic Sample Preparation with Extraction Columns) system has been coupled on-line to capillary GC-ECD by means of a loop-type interface equipped with a solvent vapour exit. Both ASPEC and GC conditions have been optimized leading to an

The analysis of pesticides is relevant to both food quality and the environment. Many laboratories are occupied with the analysis of pesticides in food, water or soil. Capillary gas chromatography is the technique most widely used in pesticide analys

Dansylation of pentachlorophenol was carried out after solid-phase extraction of acidified human serum and desorption with dichloromethane, in a dichloromethane-water two-phase system using tetrabutyl-ammonium bromide as the phase-transfer catalyst.
