I need some guidance about methane measurements on GC. what is an ideal method to make a calibration gas standard in the lab using the gas cylinder/gas bottle. we have a synthetic biogas bottle (50:50 v/v).
earlier, we used to make the calibration standard by filling the 120ml serum bottle with synthetic biogas through one needle and the air was let out with another needle (this needle was immersed under water). well there was no mass flow meter, but we used to fill the bottle with gas for about 3 minutes roughly. my new boss is not very pleased with this method. . . does anyone have any suggestions? if so, could you share it please?
will appreciate your hep.
thanks
