HIV Protease Inhibitors
 Separate six protease
inhibitors in under
4 minutes. The combination of
Hypersil GOLD(TM) 1.9 µm particles and high
linear velocity
provides a sensitive and fast assay, with baseline resolution
of all
analytes. View

Diquat and Paraquat
Hypercarb(TM) and a typical RP-LC eluent are used
to separate
quaternary ammonium salt herbicides, providing an improvement over less
sensitive ion
pairing RP-LC methods. The Hypercarb graphitic
carbon
behaves as an electron donor and retains
these cations via an
electronic interaction
mechanism. View

Direct Serum Injection for Drug Analysis
Large serum proteins cannot enter the small pores (60Å) of
the BioBasic(TM) SEC 60 column and elute
in the unretained fraction.
The three drugs are
retained via hydrophobic interactions with the
polymeric coating of the large surface area SEC particles. View
