簡單介紹
聚丁二酸乙醇酯填充柱 工作場所空氣中鄰苯二甲酸酐測定的詳細介紹
工作場所空氣中鄰苯二甲酸酐測定 詳細信息:
名稱:填充柱
固定相:聚丁二酸乙醇酯:磷酸:101 硅烷化白色擔體 = 5:1.5:100;
規格:2m*4mm
應用:GBZT 300.118-2017 工作場所空氣有毒物質測定 第118部分:乙酸酐、馬來酸酐 和鄰苯二甲酸酐
鄰苯二甲酸酐的溶劑洗脫-氣相色譜法
空氣中的氣溶膠態鄰苯二甲酸酐用超細玻璃纖維濾紙采集,丙tong洗脫后進樣,經氣相色譜柱分離, 氫焰離子化檢測器檢測,以保留時間定性,峰高或峰面積定量。
GBZ/T 300.118-2017 工作場所空氣有毒物質測定 第118部分:乙酸酐、馬來酸酐 和鄰苯二甲酸酐
本標準代替GBZ/T 160.60-2004 工作場所空氣有毒物質測定 酸酐類化合物
GBZ/T 300的本部分規定了工作場所空氣中乙酸酐的溶劑解吸-氣相色譜法、馬來酸酐的溶液吸收-液相色譜法和鄰苯二甲酸酐的溶劑洗脫-氣相色譜法。
本部分適用于工作場所空氣中乙酸酐、馬來酸酐和鄰苯二甲酸酐濃度的檢測。
浩瀚色譜(山東)應用技術開發有限公司:空氣中鄰苯二甲酸酐用玻璃纖維濾紙采集,隨即放入預先裝有2 ml丙酮的樣品瓶中,蓋塞,搖勻后用聚丁二酸乙醇酯:磷酸:101 硅烷化白色擔體 = 5:1.5:100;填充柱氣相色譜(FID)測定。鄰苯二甲酸酐濃度在0~200μg/ml范圍內線性關系良好,線性方程y=8.9+12.6x(r=0.999 9。檢出限為0.39μg/ml,若采集30 L空氣樣品,則低檢出濃度分別為0.026 mg/m3,平均加標回收率99.7%~101.4%,相對標準偏差在1.2%~3.7%。本方法適用于工作場所空氣中鄰苯二甲酸酐濃度的測定。
