i have quntified the gas sample which contain,H2O, CO2, HF,HCL,CO2,NO2 etc with the help of FTIR Gasmet DX400.. The dilution ratio was 1:10 .Nitrogen was used as a dilution gas. how can I find the real concentraion of gases .do i have to divide all the concentaraitons values with 10 or there is a different way to find the actual concentraion of all the gases ?
