Rapid and Effective Cleanup of Vitamin D2 and D3 from Human Plasma Using Phree™ Phospholipid Removal Plates and Kinetex® Core-Shell HPLC/UHPLC Columns
12 Dec 2014Vitamin D levels are often analyzed in plasma or serum samples. Recent advances in technology have included phospholipid removal products which produce cleaner samples than a protein precipitation step yet require little to no method development and very little time as compared to SPE. This application note shows the development of a rapid cleanup method for vitamin D from plasma using Phree Phospholipid Removal Plates that yielded good precision and accuracy yet was sensitive enough to analyze down to the 5 ng/mL level.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.
