Ethylene glycol analysis and detection gas chromatograph

Ethylene glycol analysis and detection gas chromatographThis machine adopts a 7-inch touch screen LCD display, which dynamically displays graphics.Pressure protection method: The carrier gas has pressure protection function. When the gas pressure drops to 0.1mpa, the instrument automatically cuts off the power supply to effectively protect the safety of the chromatographic column. Ethylene glycol, also known as ethylene glycol or 1,2-ethylene glycol, is a colorless, odorless, and sweet tasting liquid. The demand for ethylene glycol has also increased significantly, making the determination of its content very important. Ethylene glycol based substances are mainly used in the production of polyester, polyester resin, hygroscopic agents, plasticizers, surfactants, synthetic fibers, cosmetics, and as solvents for dyes/inks, antifreeze agents for engine formulations, gas dehydrating agents, and resin manufacturing.

Ethylene glycol, also known as ethylene glycol or 1,2-ethylene glycol, is a colorless, odorless, and sweet tasting liquid that is toxic. Ethylene glycol is miscible with water and acetone, but has low solubility in ethers. It can be used to synthesize polymer compounds such as polyester, and can also be used as raw materials for films, rubber, plasticizers, brake oils, etc. It is also a commonly used high boiling point solvent, and its 60% aqueous solution has a freezing point of -40 ℃. Therefore, it can be used as an antifreeze for winter car radiators and a refrigerant for aircraft engines. In recent years, the demand for polyester fibers and bottle polyester in China, Southeast Asia and other regions has grown rapidly, and the demand for ethylene glycol has also increased significantly. Therefore, the determination of ethylene glycol content is very important.
