Abstract: A GC method for determination of residual organic solvents—acetone and methanol in zinc 5-nitrosalicylate was established.A PEG-20M capillary column was used with procedural column temperature control,FID detector and nitrogen carrier.The results show that two kinds of organic solvents were completely separated with good linear relationship within the investigated concentration range(r0.999).The detection limit of methanol and acetone was 3.3 ng and 2.4 ng,with RSD lower than 5%,respectively...
