Ion mobility was integrated with liquid chromatography/high resolution mass spectrometry (LC/IM-HRMS) to quantify 25-hydroxyvitamin D (25OHD) in human serum. It has previously been shown that 25OHD adopts two gas-phase conformations which are resolve

The utility of adding ion mobility (IM) to liquid chromatography/mass spectrometry (LC/MS) for quantitation of 25-hydroxyvitamin D3 (25OHD3) is evaluated. Sodiated 25OHD3 ions adopt both closed and open conformations, whereas the stereoisomer 3-epi-2

Quantitation of the serum concentration of 25-hydroxyvitamin D is a high-demand assay that suffers from long chromatography time to separate 25-hydroxyvitamin D from its inactive epimer; however, ion mobility spectrometry can distinguish the epimer p

Ion mobility-mass spectrometry is a useful tool in separation of biological isomers, including clinically relevant analytes such as 25-hydroxyvitamin D3 (25OHD3) and its epimer, 3-epi-25-hydroxyvitamin D3 (epi25OHD3). Previous research indicates that
