质子转移反应质谱 VOC 分析仪
Research groups doing source apportionment, exhaust studies or atmospheric chemistry campaigns choose PTR-MS for speciated VOC data at sub-second speed. Hydronium ions ionize the sample softly, with detection at 10–100 ppt over m/z 20–500. The main configuration decision is the mass analyzer — quadrupole, time-of-flight or ion trap — plus whether to add a GC front end.
