This article examines the various effects of phospholipids in liquid chromatography tandem mass spectrometry (LC–MS-MS) analysis and demonstrates a new phospholipid-removal approach.
When working with complex matrices such as personal care products, sample preparation is perhaps the most difficult step of the analysis process. By utilizing a targeted sample preparation technique, such as ion-exchange SPE, analysis can be significantly improved as compared to less targeted techniques such as liquid-liquid extraction.
