Objective To establish a method for the determination of ethylene oxide residues by gas chromatography 20ml GC vials manufacturer. Methods The sample device was selected to select HS-6A headspace sampler from Shanghai Sida Analytical Instruments Co., Ltd. Wide-bore capillary column DB-5, split injection, separation at a column temperature of 50 ° C, a gasification chamber temperature of 200 ° C and a detector temperature of 200 ° C, and a nitrogen flow rate of 2.2 mL·min-1. Results The linear range of ethylene oxide was 0.3-12 μg·mL-1 (r=0.9997); the average recovery was 93.60% (r=0.9999), and the detection limit was 0.1 μg.g-1 20ml GC vials manufacturer.
This is the end of the introduction of Method for detecting ethylene oxide residue by using headspace sampler. I hope it can help you.
