forExtractionofDrugs inBiological Samples
ImproveAccuracy
UsingDerivatizationReagents
Derivatizinghard-to-chromatographcompounds, such
as activeor non-volatiledrugs, improves analytical
accuracyby increasingvolatility, reducingactivity, and
shifting retention times. Achieve lowerdetection limits
through improved response/peak shapeand
enhanced resolution!
• Available for acylation, alkylation,
and silylation.
• Packaged in10 x1gvialsor 25gvials.
