Does anyone know of a specific brand of C8 SPE cartridge
that does not contribute detectable impurities to a subsequent
OPA HPLC derivatization.

We have been unsatisfied by Varian Bond Elut, and JTBaker.

Many thanks for your suggestions.

We have been successfully using Supelco and Waters for the last two years
(without derivatization though).  Let me know if they work.
