Web10 nov. 2024 · It’s important to keep a test chromatogram, from when your column was new, to compare and understand these changes in performance over time. If resolution degrades beyond an acceptable value for good quantitation, the column should be discarded and replaced with a new one. WebThe samples are then subjected to reverse phase separation on a C18 column and analyzed by a tandem mass spectrometry method (LC-MS/MS). Quantification is achieved by comparing the responses of a given sample to the responses of the calibrators of known concentrations. The calibrators are prepared and analyzed along with the patient samples.
