HH-WAX毛细管柱 固定污染源废气 乙酸乙酯的测定的详细资料

固定污染源废气 乙酸乙酯的测定
固定污染源废气 乙酸乙酯的测定 详细信息：

名称：毛细管柱
固定液：聚乙二醇
规格：30m*0.25mm*0.5um
型号：HH-WAX
应用：固定污染源废气 乙酸乙酯的测定 气相色谱法

乙酸乙酯为无色、易挥发、易燃并带芳香气味的液体,主要用作香料和溶剂,对粘膜有中等度的刺激作用和麻醉作用.人接触较高浓度的乙酸乙酯,可引起眼、鼻、咽喉和呼吸道刺激症状.重复或长时间接触,有时可造成角膜混浊.对皮肤可引起皮炎及湿疹.高浓度可发生麻醉作用及肝、肾充血;持续大量吸入,则可发生急性肺水肿.慢性影响可有继发性贫血,白细胞增多,内脏浊肿和脂肪性变.偶有对本品发生过敏者,小量吸入后可因血管神经障碍而致牙龈出血.在溶剂的比较研究中,呼吸道阻留量,乙酸乙酯>甲苯>三氯乙烯>苯>丙酮>乙醇>乙烷.

车间空气中乙酸乙酯的测定目前尚未见报道,浩瀚色谱（山东）应用技术开发有限公司采用直接进样,聚乙二醇毛细管柱分离,氢火焰离子化检测器(FID)检测,气相色谱法测定,取得了较满意效果.





Stationary pollution source waste gas - Determination of ethyl acetate
Determination of ethyl acetate in waste gas from stationary pollution sources Details:

Name: capillary column
Fixative: polyethylene glycol
Specifications: 30m*0.25mm*0.5um
Model: HH-WAX
Application: Determination of ethyl acetate in stationary pollution source waste gas, gas chromatography

Ethyl acetate is a colorless, volatile, flammable liquid with an aromatic odor. It is mainly used as a spice and a solvent. It has moderate stimulatory and anesthetic effects on mucous membranes. Human exposure to higher concentrations of ethyl acetate can cause Eye, nose, throat and respiratory tract irritation. Repeated or prolonged contact can sometimes cause corneal opacity. It can cause dermatitis and eczema on the skin. High concentrations can cause anesthesia and liver and kidney congestion; continuous inhalation can cause acute Pulmonary edema. Chronic effects may include secondary anemia, leukocytosis, visceral opacity and fatty degeneration. Occasionally allergic to this product may cause gingival bleeding due to vascular nerve disorder after inhalation of a small amount. In the study, the respiratory tract retention was ethyl acetate > toluene > trichloroethylene > benzene > acetone > ethanol > ethane.

The determination of ethyl acetate in workshop air has not yet been reported. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts direct injection, polyethylene glycol capillary column separation, hydrogen flame ionization detector (FID) detection, and gas chromatography. measurement, and obtained satisfactory results.
