Determination of acetylene residues in grain - packed columns
Determination of acetylene residues in grain packed columns Details:

Stationary phase: styrene-divinylbenzene polymer
Specification: 2m*3mm
Model: GDX-502

Acetylene produced by the reaction of calcium carbide with water, as a fumigant to control stored grain pests, is a new technology researched in recent years. The determination of acetylene residues after grain fumigation by acetylene is an urgent problem to be solved.
According to the principle that acetylene reacts with low copper salt in ammonia solution to form red acetylene and low copper, the colorimetric method is used to determine the residual amount of acetylene in grain, which is time-consuming and laborious and inefficient.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. developed a gas chromatography method to determine the residual amount of acetylene in grain. The external standard method was used to quantify the results.
