Short Column GC/MS with Increased Analysis Speed by Peak-Hopping

摘要

Speeding up analytical time is the best to enlarge the profit from GC/MS (gaschromatography/mass spectrometry) analysis. Especially in field applications like emergency response with mobiel GC/MS high speed analysis are demanded. GC separation is done with short capillary columns and optimized temperature programs consisting of extremely high heating rates. GC/MS analysis of organic mixtures are performed in less than 2 min. For this purpose a new infrared heated GC has been developed. A mximum heating rate of 1000 deg C/min in a temperature range up to 300 deg C is achieved The sample throughput is raised by factor 5 to 20 compared to fast GC/MS or normal laboratory methods.
