摘要：

A dynamic dilution system, utilizing single dilution, is described that generates sub ppb concentration of impurities in bulk nitrogen. An atmospheric pressure ionization mass spectrometer (APIMS) is used to verify the linearity of the dilution system. This system is used to obtain limits of detection of a commercially available single quadrupole APIMS for detecting methane, moisture, oxygen, and carbon dioxide in high purity nitrogen.
