People who are engaged in chemical industry all know what it is. Many foreign industries may be confused. People's life is "never too old to learn". So, here is the time for us to learn thin layer chromatography silica gel plate together.
High purity thin layer chromatography silica gel is sprayed with a certain amount of binder to make a thin layer chromatography silica gel plate. Its surface is fine, pure white and even. The main component is the composition of silica and water, but its chemical properties are very stable, and it does not react with other acid-base substances, except hydrofluoric acid and strong base.
Thin layer chromatography silica gel plate can be directly used in the quantitative or qualitative analysis of various types of organic substances, and has been widely used in the identification of food trace impurities, medicine, organic chemical products, pesticides, grains and Chinese herbal medicines. At present, it is also used in POM class of new material POM rod, and it also plays an important role in judging gutter oil. It is characterized by good separation effect, clear spots, non-proliferation and high sensitivity. It is precisely because of these characteristics that it "gets mixed" in the market.
If you want to prepare thin-layer chromatography silica gel plate by yourself, you need a lot of experience to support it. You need to pay attention to the speed of liquid flowing down. When you operate, you need to pay attention to the thickness evenly and uniformly spread on the carrier plate, and then spoon it into the middle part of the carrier plate to slowly cover the whole plate. At last, use your hands to gently vibrate it for several times. You need to pay attention not to There are blisters.
