GDX-502填充柱安捷伦7820A使用
GDX-502填充柱安捷伦7820A使用 详细信息：

名称：填充柱
固定相：高分子小球
规格：2m*3mm
型号：GDX-502
应用：
1.非甲烷总烃的甲烷柱
2.吸附剂
3.乙烯，乙烷，乙炔的分离
4.焦炉煤气，炼厂气，天然气，变压器油，中CO2,C2分离

电石法醋酸乙烯是通过以乙炔和乙酸作为原料，活性炭吸附醋酸锌为催化剂合成而得，在合成反应器、醋酸蒸发器以及气体分离塔检修作业中，涉及受限空间作业分析的有乙炔、氧气和醋酸乙烯等易燃易爆气体。《中华人民共和国国家标准—化学品生产单位特殊作业安全规范》gb30871-2014中要求受限空间作业检测中，氧气含量18％～21％，富氧环境下不得大于23.5％，可燃气体浓度：当被测气体或蒸气的爆炸下限小于4％时，其被测浓度不大于0.2％。(乙炔爆炸下限2.55％，醋酸乙烯爆炸下限2.6％)，因而要求被测浓度小于0.2％。

浩瀚色谱（山东）应用技术开发有限公司采用气相色谱双通道的通道分别检测氮氧及乙炔含量，面积外标法定量，结果满意。

GDX-502 packed column used by Agilent 7820A
GDX-502 Packed Column Agilent 7820A Use Details:

Name: Packed Column
Stationary phase: polymer beads
Specifications: 2m*3mm
Model: GDX-502
application:
1. Methane column of non-methane total hydrocarbons
2. Adsorbent
3. Separation of ethylene, ethane and acetylene
4. Coke oven gas, refinery gas, natural gas, transformer oil, CO2, C2 separation

Calcium carbide vinyl acetate is synthesized by using acetylene and acetic acid as raw materials, and activated carbon adsorbs zinc acetate as catalyst. In the overhaul operations of synthesis reactors, acetic acid evaporators and gas separation towers, acetylene and oxygen are involved in the analysis of confined space operations. and flammable and explosive gases such as vinyl acetate. "National Standard of the People's Republic of China - Safety Specifications for Special Operations of Chemical Production Units" gb30871-2014 requires that the oxygen content in the inspection of confined spaces should be 18% to 21%, and not greater than 23.5% in an oxygen-enriched environment. The concentration of combustible gas: when When the lower explosion limit of the tested gas or vapor is less than 4%, the tested concentration is not more than 0.2%. (The lower explosion limit of acetylene is 2.55%, and the lower explosion limit of vinyl acetate is 2.6%), so the measured concentration is required to be less than 0.2%.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used the first channel of the dual-channel gas chromatography to detect nitrogen, oxygen and acetylene content respectively, and the area external standard method was used for quantification, and the results were satisfactory.
