饲料添加剂中总丙酸含量检测毛细管柱PEG-20M
饲料添加剂中总丙酸含量检测毛细管柱PEG-20M 详细信息：
丙酸是一种挥发性脂肪酸，为无色透明液体，易溶于水、乙醇、乙酸乙酯等溶剂。它是动物正常代谢的中间产物，具有很广的抗jun谱，通常用于配制饲料防霉剂和酸化剂。由于丙酸的挥发性较强，单独添加丙酸其作用时间短，因此饲料防霉剂中往往同时添加丙酸盐，饲料防霉剂中常见的丙酸盐为丙酸铵、丙酸钙、丙酸钠和丙酸钾。丙酸盐在酸性条件下会持续游离出丙酸以发挥防霉作用。

Determination of total propionic acid content in feed additives Capillary column PEG-20M
Determination of total propionic acid content in feed additives Capillary column PEG-20M Details:
Propionic acid is a kind of volatile fatty acid. It is a colorless transparent liquid and is easily soluble in water, ethanol, ethyl acetate and other solvents. It is an intermediate product of normal metabolism of animals and has a wide anti jun spectrum. It is usually used to prepare feed fungicides and acidifiers. Due to the strong volatility of propionic acid, the action time of adding propionic acid alone is short, so propionate is often added to feed fungicides at the same time. The common propionate in feed fungicides are ammonium propionate, calcium propionate, sodium propionate and potassium propionate. Propionate will continuously free propionic acid under acidic conditions to play a role in mold prevention.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a gas chromatography method for the determination of total propionic acid in feed additives. The pretreatment is simple, the reagents used are safe and non-toxic, the safety of detection personnel is high, the results are accurate and stable, and the damage to the instrument can be reduced.
