Short summary
PTR-MS is widely used in atmospheric sciences for the detection of non-methane organic trace gases. The two most widely used types of PTR-MS instruments differ in their ion source and drift tube design. We herein present a new prototype PTR-MS instrument that hybridizes these designs and combines a conventional hollow cathode glow discharge ion source with a focusing ion–molecule reactor. We also show how this new instrument performs in detecting atmospheric amines.
