乙酸酐空氣監測填充柱
乙酸酐空氣監測填充柱 詳細信息：

名稱：填充柱

固定相：2，6－二苯基對苯醚的多孔聚合物擔體

規格：2m*4mm

材質：玻璃柱/不銹鋼

型號：Tenax

應用：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

浩瀚色譜（山東）應用技術開發有限公司對空氣中乙酸酐的氣相色譜測定方法進行了規范化研究。并對某廠生產乙酸酐的車間進行了勞動衛生學的調查 ,于 2年時間內兩次對乙酸酐生產車間工人經常停留的地點進行采樣 ,應用氣相色譜法分析。成品包裝與泵房二處作業地點空氣中乙酸酐的平均濃度分別為2 3.1 mg/ m3和 2 6.0 mg/ m3,濃度范圍為 1 9.6～ 31 .5mg/ m3,工人中眼干、眼灼痛、流淚等癥狀的發生率明顯高于對照組和其它工種的工人。

Acetic anhydride air monitoring packed column
Acetic anhydride air monitoring packed column Details:

Name: Packed column

Stationary phase: porous polymer support of 2,6-diphenyl-p-phenylene ether

Specification: 2m*4mm

Material: glass column/stainless steel

Model: Tenax

Application: GBZ/T 300.118-2017 Determination of Toxic Substances in Workplace Air Part 118: Acetic Anhydride, Maleic Anhydride and Phthalic Anhydride




Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. conducted a standardized study on the gas chromatography determination method of acetic anhydride in the air. In addition, an occupational hygiene investigation was carried out on the acetic anhydride workshop of a certain factory, and the places where workers often stay in the acetic anhydride production workshop were sampled twice in 2 years and analyzed by gas chromatography. The average concentration of acetic anhydride in the air of the finished product packaging and the pump room was 2 3.1 mg/m3 and 2 6.0 mg/m3, respectively, and the concentration range was 1 9.6-31.5 mg/m3. Workers had dry eyes and burning eyes. The incidence of symptoms such as tearing and tearing was significantly higher than that of the control group and other workers.
