The solid phase extraction device developed and produced by Shanghai Xinzhuang is energy-saving and environmentally friendly, leading domestically.
In the solid phase extraction apparatus of Shanghai Xinzhuang Instrument Co., Ltd., in solid phase extraction, the adsorption of solid relative to the separation material is larger than that of the solvent. As the sample solution passes through the adsorbent bed, the isolate concentrates on its surface and the other sample components pass through the adsorbent bed; high purity and concentrated isolates are obtained by adsorbing the adsorbate only by adsorbing the isolate without adsorbing other sample components.
Retention and elution: The most common method in solid phase extraction is to mount the solid adsorbent in a syringe-like column, passing the sample solution through the adsorbent bed, and the compound in the sample either passes through the adsorbent or remains on the adsorbent. (depending on the relative adsorption of the adsorbent to the solvent). "Retention" is a phenomenon of attraction between the adsorbent and the molecules of the separator, such that when the sample solution passes through the adsorbent bed, the isolate does not move on the adsorbent. Retention is the role of three factors: the separation, the solvent and the adsorbent. Therefore, the retention behavior of a given isolate varies in the presence of different solvents and adsorbents. "Elution" is the process of removing the separation of the separation agent from the adsorbent by adding a solvent that attracts the separation material more strongly than the adsorbent.
