The NovaCHROM 5000 GC from AGC Instruments, using a Double Flame Photometric Detector (FPD), detects and identifies individual sulphur species in CO2 Sources for use in the Food & Beverage industry (to ISBT, EIGA and CGA Standards). Sulphurous species such as H2S, COS, CS2, Mercaptans and Sulfides can be measured with sensitivity to low ppb levels and highly accurate and stable results combined with longevity of use.
