| Abstract: | Microcoulometer was applied to the determination of sulfur content in dimethyl adipate sample. The temperature of vaporizer of 600℃, the temperature of eombustor of 800℃, offset voltage of 150 mY, yield value of 200 and sampling resistance of 2 kΩ were set to determine the sulfur content. With inlet amount of 8.0μL, after five determination of 10ng/μL standard solution, average conversion obtained was 102%, average sulfur content in dimethyl adipate sample obtained was 8.70 ng/μL and RSD of the results was 2.64 %. |
