Title: what are the differences between extraction procedures?
Post by: trucmi0403 on May 19, 2007, 01:57:29 PM

there are so many procedures to seperate analytes from aquaeous matrices such as solid-phase extraction, SPME, liqiud-gas extraction, liquid-liquid extraction,...  what are the differences between them ? :)

Actually, dfx have provided the general difference
