Mass Spec Calibrations

Biopharmaceutical and pharmaceutical companies throughout California rely on the team at GL Technologies for their mass spectrometry calibration needs. Mass spectrometry is a critical process in analytical chemistry that verifies the accuracy and precision of mass spectrometers, which are vital tools for identifying and quantifying chemical compounds in various samples. Calibration involves adjusting the instrument’s settings and parameters to align the measured “mass-to-charge (m/z)” of ions with their known values. We achieve this alignment by introducing a known standard compound into the mass spectrometer and adjusting its parameters until the measured mass spectra match the expected values. For biopharma and pharmaceutical organizations, proper calibration not only increases the reliability of analytical results but also allows for the detection of subtle differences in molecular masses, making it indispensable in these industries.
