粮食中乙炔残留量的测定填充柱
粮食中乙炔残留量的测定填充柱 详细信息:
碳化钙与水反应产生的乙炔,作为熏蒸剂来防治储粮害虫,是近几年来研究的一项新技术.粮食经乙炔熏蒸后,乙炔残留量的测定是亟待解决的一个问题.
根据乙炔在氨溶液中与低铜盐作用生成红色的乙炔低铜的原理,应用比色法测定粮食中乙炔残留量, 费时费力,效率低下。
滕州市浩瀚色谱仪器技术服务有限公司,研发出气相色谱法测定粮食中乙炔残留量,外标法定量,结果满意。

Determination of acetylene residues in grain - packed columns
Determination of acetylene residues in grain packed columns Details:
Statio nary phase: styrene-divinylbenzene polymer
Specification: 2m*3mm
Model: GDX-502
Acetylene produced by the reaction of calcium carbide with water, as a fumigant to co ntrol 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 ammo nia 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-co nsuming 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.
