I'm looking for information on Solid Phase Extraction.  I run an HP
6890 GC, 5973 MS with autosampler.  I have all of the equiptment needed
(evaporator, vacuum aparatus), what I need is recommended types of
tubes as well as appropriate solvent systems.  My work is with urine
based drugs of abuse.  Specificially, I'm looking for:
TCA's, cocaine, opiates, amphetamines(including methamp), barbs,
benzos, pcp, and methadone.  Any information would be greatly
appreciated, even if you can only point me in the right direction.
