Queued and Ready to Run? Testing the Stability of Vitamin Extracts While in Queue Using Triple Quadrupole LC/MS/MS Analysis

摘要

Each of these vitamin species demonstrate a loss of signal which continues to diminish with time. This trend complicates the practice of extracting samples in bulk and setting vials in an autosampler rack for an extended duration prior to analysis. Reducing sample run time using UHPLC online with an ultrafast mass spectrometer will prove crucial to minimizing intra- and interday results when making quality control analyses for these analytes.
