Development of a Residual Gas Analyzer Calibration System

S. S. Hong,I. T. Lim,J. T. Kim


The Korea Research Institute of Standards and Science (KRISS) has developed a residual gas analyzer (RGA) calibration system and measured gas sensitivities for two different types QMSs using nitrogen, argon, and helium. Different gas sensitivities were identified according to mass and pressure, so it was revealed that the gas sensitivity correction is necessary for proper use of mass spectrometers.
