Welchrom C18E, 500mg/3mL, 50pcs/pk Buy Cheap Visit

Welchrom C18E SPE cartridge applies endcapped C18 sorbent which is the most hydrophobic silica based adsorbent. It has excellent retention ability for non-polar compounds and most organic substances. Because C18 could retain most of the organic substances in the water-soluble matrix, so it has the least selectivity and is often used to treat samples that contain a variety of structures or structures that vary widely. Besides, C18E can’t retain the salt completely, it is usually to use a C18E cartridge instead of an ion exchange column to desalinate some small molecules and some medium-sized molecules.
