【C09】Gas Concentration Measurement System for Low Carbon Fuels

Calibrated Device 
(1) Special Concentration in Synthetic Natural Gas
(2) Gas Concentration in Binary Gas Mixtures (CH4/N2, C3H8/N2 CO2/N2)
(1) The concentration of the gas to be calibrated is verified by using a synthetic natural standard gas with metrological traceability.  The concentration of the executable verification is based on the concentration range of natural gas standards that the laboratory has.  The main component gas with a concentration greater than 1% can be verified to a concentration between 1/2 to 2 times of the standard gas concentration.
(2) CH4 in N2: 0.1 cmol/mol to 10 cmol/mol    
     C3H8 in N2: 0.1 cmol/mol to 5 cmol/mol    
     CO2 in N2: 0.1 cmol/mol to 16 cmol/mol
Uncrtainty  (1) 0.2 % to 1.2 %
(2) 0.5 % to 1.0 %
