Hydrocarbons are widely found in industry and daily life. They bring certain benefits to people's lives, but also have problems such as polluting the environment, flammable and explosive. If a certain amount of hydrocarbons are mixed in a high-purity gas, it will not only affect the normal use of high-purity gas, but also pose a threat to life safety in serious cases. Therefore, it is necessary to measure the total hydrocarbons in high-purity gas to control The quality of the product reduces the hazard.
The meaning of "total hydrocarbon" In organic chemistry, the definition of hydrocarbon refers to a compound composed only of two elements of hydrocarbon, and the alkane, alkene, alkyne, and benzene compound belong to a hydrocarbon. Alcohols, aldehydes, acids, esters, ketones and the like do not belong to hydrocarbons because they contain heteroatoms. In fact, the current total hydrocarbon analyzer has a strong response to the above compounds. So, can we replace the total hydrocarbons with the concept of total organic compounds?
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. used a capillary column to determine the content of hydrocarbons (total hydrocarbons) in high-purity argon gas with satisfactory results.
