Short summary
This work developed voltage scanning based calibration approach for a multi-reagent chemical ionization mass spectrometry. This approach improves sensitivity determination for gas-phase compounds. It does not require a calibrant for the target analyte and can estimate sensitivity with acceptable uncertainty based on the experimentally established relationship between binding energies and measured sensitivities. This work is broadly relevant to mass-spectrometric calibration strategies.
