采用气相色谱法,用7%SE-30 chromosorb DMCS 150~180μm(3 m×3 mm)填充柱,以正壬烷为内标物,用氢火焰离子化检测器对邻羟基苯甲腈和邻羟基苯甲酰胺进行定量分析;结果表明,该分析方法的对邻羟基苯甲腈、邻羟基苯甲酰胺的线性相关系数分别为0.9998、0.9991;标准偏差分别为0.25、0.04,回收率分别为99.7%~100.2%、98.0%~101.4%。
採用氣相色譜法,用7%SE-30 chromosorb DMCS 150~180μm(3 m×3 mm)填充柱,以正壬烷為內標物,用氫火燄離子化檢測器對鄰羥基苯甲腈和鄰羥基苯甲酰胺進行定量分析;結果錶明,該分析方法的對鄰羥基苯甲腈、鄰羥基苯甲酰胺的線性相關繫數分彆為0.9998、0.9991;標準偏差分彆為0.25、0.04,迴收率分彆為99.7%~100.2%、98.0%~101.4%。
채용기상색보법,용7%SE-30 chromosorb DMCS 150~180μm(3 m×3 mm)전충주,이정임완위내표물,용경화염리자화검측기대린간기분갑정화린간기분갑선알진행정량분석;결과표명,해분석방법적대린간기분갑정、린간기분갑선알적선성상관계수분별위0.9998、0.9991;표준편차분별위0.25、0.04,회수솔분별위99.7%~100.2%、98.0%~101.4%。
The sample is dissolved in methanol,using FID detector and 3 m×3 mm(id) glass column packing with 7% SE-30/chromosorb DMCS,salicylonitrile and salicylamide can be separated and determined with n-nonane as internal standard.The results: for salicylonitrile,the relation coefficient,the relative standard deviation and the recoveries were 0.9998,0.26% and 99.7%~100.2% respectively;for salicylamide,0.9991,2.2% and 98.0%~101.4% respectively.
