Nutech Ambient Air Online VOCs Monitoring Solutions
Nutech offers several solutions to monitor VOCs in ambient air based on different monitoring targets and different technologies.
NCMS 6300 is for THC & NMHC online monitoring using LTP + FID technology.
VsCMS 6500 is for PAMS compounds online monitoring using LTP + GC-FID technology.
VsCMS 6600 is for 117 VOCs species online monitoring using LTP + GC-FID/MS technology.
VsCMS 6700 is for 117 VOCs species online monitoring using LTP + GC-TOF technology.

Working Principle of Nutech Online VOCs Monitoring Systems
The ambient air enters into the sampling unit of the online monitoring system at a constant flow rate. The VOCs are enriched and pretreated by low temperature trap, and then separated by gas chromatography through thermal desorption and detected by hydrogen flame ionization detector (FID) or mass spectrometry detector (MSD/TOF-MS). Therefore, the concentrations of total hydrocarbons (THC), non-methane hydrocarbons (NMHC) and each VOCs species are obtained.
