What Is a Sorbent Tube?

Plasma adsorption means that after the blood is drawn out, it first enters the plasma separator to separate the blood's constituents (blood cells, platelets) from the plasma, and the constituents are returned to the patient. Back into the patient. Plasma adsorption is mainly divided into two categories based on the characteristics of the adsorbent. One is molecular sieve adsorption, which uses the principle of molecular sieve to carry the charge and pores carried by the adsorbent through non-specific adsorption on substances corresponding to the charge and molecular size. Activated carbon, resin, carbonized resin, cationic adsorbent, etc .; the other is immunoadsorption, which uses a highly specific antigen-antibody reaction or a substance (ligand) with a specific physicochemical affinity to bind to the adsorbent (carrier) In addition, it is used to remove specific substances (ligands) in plasma or whole blood, such as protein A adsorption, bilirubin adsorption, and so on.
