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.
