 Scale : USA Standard Gas (NIST)
Performed every month using computer-controlled massflow dilution of a standard gas mixture (CO, CH4, CO2, and C3H8 ; C3H8 representing NMHC) at 6 individual levels for each component in its relevant concentration range.

 A Chromo-pack GC is operated with three columns in series, packed with HayeSep and Molecular sieve. Following sample injection, backflush and heat-cut techniques are performed using two 10 port switching valves. After separation, components are led to a hydrogen-fed Ni catalyst (methanizer) where CO2 and CO are converted to CH4. Final detection is done by means of a flame ionization detector(FID).
