Instruments for monitoring ozone-depleting substances and greenhouse gases

Monitoring ozone-depleting substances (ODS) and halocarbon greenhouse gases (GHGs) can be challenging because of varying concentration ranges and ultra-volatile nature of target species, interference from water and CO₂, and laboratory and unattended field measurements is required.

Designed for scientists monitoring ODS and GHGs in air, Markes’ portfolio of preconcentration instruments for GC–MS addresses these challenges by facilitating the monitoring of key species in any environment, with method detection limits ranging from ppm to sub-ppt.
