Mass Spectrometry for Real-Time Gas Analysis
Posted on March 16, 2026 Physical Modeling
Abstract
This paper presents a calibration approach for quadrupole mass spectrometry used in real-time gas analysis, with emphasis on correcting species-dependent ionization effects through empirically determined relative sensitivity factors. Using a certified span gas containing nitrogen, oxygen, argon, and helium, the method shows that calibrated measurements converge closely to known gas compositions and reproduce expected ambient air concentrations. The results demonstrate improved accuracy and reliability in time-resolved gas concentration measurements for industrial and research applications.
