Method development of an extraction of polar pesticides from peach - Comparison of CHROMABOND

Summary

Type: SPE
Application #: 304450
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% phosphoric acid solution of pH 2 Sample aspiration: With tubing adaptor (e.g. CHROMABOND® tubing adaptor, MN-Cat. No. 730243)
