500g/L莠去津悬浮剂测定玻璃柱 详细信息：

名称：不锈钢柱或玻璃柱
固定液：3%聚乙二醇-20M
载体：Gas Chrom Q
粒度：80-100目
应用：GB/T 22608-2008 莠去津悬浮剂


为了解决高含量莠去津悬浮剂容易析水的问题,利用流点法对莠去津悬浮剂的分散剂进行初步筛选,根据Zeta电势和粒径大小,进行优化组合确定了分散剂的种类和用量;在此基础上,结合莠去津悬浮剂热贮后的物化性能,确定了500g/L莠去津悬浮剂的配方为莠去津原药46.5%、SD-208为4%、乙二醇4.0%、黄原胶0.15%、有机硅消泡剂0.1%、苯甲酸钠0.1%、去离子水补足,结果表明,该产品热贮14d后,悬浮率95%以上,分解率5%,其他各项指标均符合悬浮剂的要求。

Glass column for the determination of 500g/L atrazine suspension
Glass column for determination of 500g/L atrazine suspending agent Details:

Name: stainless steel column or glass column
Fixative: 3% polyethylene glycol-20M
Carrier: Gas Chrom Q
Particle size: 80-100 mesh
Application: GB/T 22608-2008 atrazine suspension


In order to solve the problem that high-content atrazine suspension agent is easy to separate water, the flow point method is used to initially screen the dispersant of atrazine suspension agent. According to the Zeta potential and particle size, the optimal combination is determined to determine the best dispersant. Type and dosage; on this basis, combined with the physical and chemical properties of the atrazine suspending agent after heat storage, the best formula of 500g/L atrazine suspending agent is determined to be 46.5% of atrazine original drug and 4% of SD-208. , Ethylene glycol 4.0%, Xanthan gum 0.15%, Silicone defoamer 0.1%, Sodium benzoate 0.1%, and deionized water make up. The results show that the product has a suspension rate of more than 95% and a decomposition rate of 5 after being stored for 14 days. %, other indicators meet the requirements of suspending agent.


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used a glass column and internal standard method to determine 500g/L atrazine suspension, with satisfactory results.
