Background/Objective: A direct, accurate, precise, reproducible and cost-time efficient
approach for calibration of HPLC using mass spectrometer as detector has been described
which simulates the routine analysis in bioanalytical laboratories.
Methods: Injector position check and injection volume repeatability test for the calibration
of autosampler; and pump flow rate accuracy test for the calibration of pumps were
illustrated using direct weighing method. Carryover test, pump repeatability test, linearity
and precision were carried out for holistic (overall system) calibration of the instrument
using a sensitive high throughput LCeMS/MS pre-validated method.
Results/Conclusion: The results of calibration experiments for individual modules suggested
that pumps are yielding accurate flow rate, autosampler is aspirating the correct injection
volume irrespective to position or volume, and column oven and autosampler chambers
are maintaining steady temperatures. Holistic calibration verified the accuracy, precision,
repeatability and reproducibility of the instrument with insignificant carryover.
