卷烟主流烟气中8种羰基化合物的超高效液相色谱测定
Determination of Major Carbonyls in Mainstream Cigarette Smoke by Ultra Performance Liquid Chromatography
摘要
Abstract
An Ultra Performance Liquid Chromatographic (UPLC ) method was developed for the separation and determination of formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde, crotonaldehyde, 2-butanone, butyraldehyde in cigarette mainstream smoke. The targeted compounds in cigarette mainstream smoke were collected with a Cambridge fliter treated with acidic solution of 2, 4-dinitrophenylhydrazine, and extracted with 50 Ml 2% pyridine acetonitrile. The carbonyl compounds were separated on a KinetexTM C18 (150 mm ×2. 1 mm, 2. 6 μm) column, using water - acetonitrile (35 : 65) mixed solution and water - acetonitrile - tetrahydrofuran - isopropyl alcohol (59 : 30 : 10 : 1) as mobile phases by gradient elution. The eight carbonyl compounds were separated in 20 min and determined by UPLC with a diode array detector. The result indicated that the correlation coefficients (r ) of eight carbonyl compounds were not less than 0. 999 97. The detection limits for the method were between 25. 81 ng/cig and 67. 74 ng/cig. The average recoveries were in the range of 95% -99% with relative standard deviations of 1. 4% -5. 8% . Compared with the YC/T 254 -2008 standard method, the proposed method was faster, simpler and less consumption, and was applied in the determination of eight carbonyl compounds in twenty kinds of cigarette with satisfactory results.关键词
