Liquid fully automated sample treatment

One analytical technique especially suited to pesticide analysis is high performance liquid chromatography (HPLC), and one particular version of it is called FAST-LC (an acronym for Fully Automated Sample Treatment for Liquid Chromatography). It is the various aspects of this automated sample treatment which will be considered in this report. 

The versatility of the design of an analytical pervaporation module, attributable to its changeable donor volume and the air gap present above the sample, has enabled its use with liquid, solid, and semisolid samples. Table 1 summarizes the applications of analytical pervaporation and the main fields in which it has been used. The manifold used and the way in which the sample is introduced in the system vary depending on whether it is liquid or solid. The main difference between the treatment of liquid and solid samples is the fact that with liquids the whole pervaporation process, from sample introduction to delivery of the results can be fully automated, while some operator s intervention is needed when dealing with solids.
