分析解決方案-

食品級CO2中含氧化合物及苯的91福利片导航网測定


一、方法概述：

本方法測定食品級CO2中氯乙烯，乙醛，環氧乙烷，甲醇和苯的含量，將氣體樣品通過進樣閥導入具有氫火焰離子化檢測器FID的91福利片导航网，在專用的氣相毛細管色譜柱上分離，一次進樣得到各組分的含量結果。該方法滿足食品安全國家標準《GB1886.228-2016 食品添加劑 二氧化碳》中的相關檢測要求。


二、實驗儀器，器材及標準物：

G51（FID）91福利片导航网；六通進樣閥

標準樣品：苯/2.2ul/L，甲醇/104ul/L，乙醛/21.2ul/L，環氧乙烷/10.2ul/L，氯乙烯/31.2ul/L；

N2純度>99.999%

空氣：無油空氣發生器（XGA-380A）

氫氣：高純氫氣發生器（XGH-300）

采樣容器：100玻璃針筒，5#針頭
