离子色谱法测定酒中的有机酸和无机阴离子
Determination of Organic Acids and Mineral Anions in Liquor by Ion Chromatography
摘要
Abstract
A new method was established to determine organic acids and mineral anions in liquor by ion chromatography with conducting detection. The samples were diluted by water and filtrated with 0.45 um membrane. The samples solution were injected and analysized. Ionpac ASH was selected as the separation column. The gradient KOH solution with a flow rate 1.0 mL/min was used as eluent. Auto-generated conducting detection ASRS-4mm was used. The method had good relativity (the correlative coefficients(r) were 0.9909-0.9997). and the extraction recoveries were 81.0-117.8%. In addition, the RSD were less than 5.0%. and the detection limits were 0.015-0.152 mg/L. The method had a wide linear range, good repeatability and accuracy.关键词
