Recommended Procedures for HybridSPE™ - Precipitation (HybridSPE-PPT) 96-well Plates & Cartridges
01 Sep 2008: It is well known that phospholipid contamination is one of the principal causes of ion-suppression when analyzing small molecules in biological matrixes via LC-MS-MS. HybridSPE - Precipitation technology is a simple and generic sample prep platform designed for the gross level removal of endogenous protein and phospholipid interferences from biological plasma and serum prior to analysis. Two methods are available: an "In-Well Precipitation" method and an "Off-line Precipitation" method.

Comparative Extraction and LC-MS-MS of 10 ng/mL Clenbuterol (R(-) and S(+) enantiomers) in Rat Plasma
01 Sep 2008: In this application example, rat plasma samples were spiked with clenbuterol (R(-) and S(+) enantiomers) at the level of 10 ng/mL and extracted using three different procedures: Hybrid- SPE-PPT, Protein PPT, and a 9-step SPE procedure optimized for trace level clenbuterol analysis. Comparisons of sample preparation methods were made in terms of the amount of phospholipids in the sample extract and the overall effect on signal response of clenbuterol enantiomers.
