450 GC COUPLED WITH PFPD AND FID
PFPD - we are using to find out the sulfur components from 1-100 ppm. It will inculde the all mercaptans upto hexyl mercaptan, Hydrogensulfide, carbonyl sulfide,sulfur dioxide.
But in our case the standard will take more than 10 runs to get the stable reading , also our sample which we are blending that showing only less value instead of 3 ppm only showing 0.8 ppm.
Everyone recommending GC for the sulfur analysis but in our case it is not favour for us. For the past one year we are facing this problem.
Please try to help me.
