Answer Posted / nidhi srivastava
In the majority of the cases the analytical method of
choices is either GC or HPLC. GC generally selected where
the compounds to be analysed are volatile, of low molecular
weight, thermally stable and non polar.In HPLC methods
developed for analytical work with picograms, nanograms of
compounds are simply transferred to larger columns to higher
flow rates for preparative chromatography for the isolation
of milligrams or grams of compounds. Similar scale
preparative GC would be impractical, if not impossible, in
the laboratory.
