Product overview

EXPEC-2000 Series Methane/NMHC/THC analyzer uses dual-column, dual-valve switching technology, and hydrogen flame ionization detector(FID)technology for the detection of methane and non-methane hydrocarbons.

EXPEC-2000 Series BTEX analyzer adopts cold temperature enrichment and high-temperature thermal desorption technology for sample enrichment, and the detector adopts FID technology to measure BTEX.
