摘要

戊二醛(GA)通常用于工业、农业、医疗保健、实验室等领域的表面和设备消毒。为评价GA产品的质量，建立了2,4-二苯肼衍生物的高效液相色谱法。用CN柱分离，乙腈与磷酸的等比重为0.1%(比例为50:50)，PDA检测器检测，波长为360 nm。验证了该方法的专属性、线性曲线、精密度和准确度均满足AOAC的要求。

High performance liquid chromatography analytical method for glutaraldehyde determination in disinfectants

Glutaraldehyde (GA) is commonly used to disinfect surfaces and equipment in industries, agriculture, healthcare, laboratories, etc. To evaluate the quality of products containing GA, a HPLC method using 2,4-diphenylhydrazine derivative was developed. The analyte was separated by CN column with isocratic of acetonitrile and phosphoric acid 0,1% (ratio 50 : 50) and detected by PDA detector using a wavelength of 360 nm. The method was validated for specificity, linear curves, precision and accuracy which meet the requirements of AOAC.
