Minimizing Phospholipid Interference During LC-MS/MS Analysis of Vitamin D Metabolites in Serum for Clinical Research
28 Nov 2018Interferences by matrix components can be challenging when measuring serum levels of vitamin D metabolites by LC-MS/MS, particularly lysophosphatidylcholines. They are challenging to remove during sample preparation and difficult to separate chromatographically. This white paper describes an approach for method optimization using the Oasis PRiME HLB solid phase extraction plate, from Waters.

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.
