15/3/2014 · LC/MS/MS has become the method of choice for 1,25-(OH) 2-D 2 and -D 3 analysis due to its sensitivity and repeatability .The active form of vitamin D circulates in much lower levels than 25-OH-D .Though 25-OH-D is in the ng/mL range, 1,25-(OH) 2-D 2 and -D 3 are in the low pg/mL range, necessitating sensitive RIA or LC/MS/MS methods. . However, even LC/MS/MS methods are limited in sensitivity

15/10/2019 · The LC-MS/MS method has been evaluated for PEth 16:0/18:1 with respect to selectivity, LOQ, limit of detection (LOD), linearity, precision, accuracy, carryover, robustness, and matrix effects. The method evaluation has also included a comparison with the previously used HPLC method.
