Ultra-low Detection Limits for Trace Gas Analysis Using a Tunable Non-radioactive Electron Emitter in APCI-MS

摘要

In many fields of application an analytical tool for trace gas analysis is needed that combines high selectivity with ultra-high sensitivity and minimal response time. One approach to achieve these requirements is coupling an atmospheric pressure chemical ionization source, which can provide ultra-high sensitivity for most volatile organic compounds to a time-of-flight mass spectrometer with sufficient mass resolution in the range of 30 to 300 Da.
