Summary
Type: SPE
Application #: 304500
Catalog#: 730108 - SPE Cartridges, Chromabond, HR-P, 3ml, PP, 200mg 30/pk
Detection: The extracted sample is determinated by LC/ESI-MS/MS by a polar RP column (e.g. NUCLEODUR® C18 Pyramid) with methanol / 10 mM ammonium acetate gradient.
Conditions: CHROMABOND® HR-P:
Column conditioning: 3 ml methanol, then 3 x 3 ml 0.1% H3PO4; after first 6 ml H3PO4 solution the valve is closed.
Sample aspiration: In a volumetric flask the water/methanol ext
