The oxygen concentrator is a kind of machine that produces oxygen, and its principle is to use air separation technology. The air is compressed with high density and then the difference in the condensation point of each component in the air is used to separate it from gas and liquid at a certain temperature, and then it is separated into oxygen and nitrogen by rectification. Next, let's take a look at what is the difference between oxygen concentration 3l and oxygen concentration 5l? Here are some answers. Read More

When the human body is infected with a virus, immune cells are stimulated to produce specific antibodies. The two main types of specific antibodies produced include IgM antibodies and IgG antibodies. The former is produced in the initial immune response and is produced quickly and for a short period, while the latter is produced in the secondary immune response and is produced late and for a long period. Rapid immunoassay tests are mostly performed on test strips, and most of them apply the colloidal gold principle of antigenic antibodies. Let me introduce the novel coronavirus (SARS-COV-2) lgG/IgM antibody test kit (colloidal gold method) in detail next! Read More
