C18

C18 is a reversed-phase sorbent based on silica gel, with high bonding density, less lost, high rate of recovery.

Application:

1.Drugs and its metabolin in blood, plasma and urine

2.Desalination of samples of protein and macromolecule

3.Concentration of organic material in water sample from the environment

4.Organic acid in beverage

5.Similar to reversed phase HPLC Column, suitable for extracting and purifying antibiotics, barbiturates, phthalazine, caffeine,dye, aromatic oil,fatsoluble vitamin,fungicide,herbicide,pesticide,carbohydrate,Hydroxy acid substituted ester,phenol,phthalic acid ester,steroid,surfactant,theocin,water-soluble vitamin.

C8

C8 has very close characteristics with C18, but it has short carbon chain, thus it has week reservation than C18 to non-polar compound. When analyte has too strong reservation on C18, C8 is an alternative choice. In the meantime, as C8 has shorter carbon chain, it can’t cover the Residual Silanol Groups on the surface of silica gel. Thus it has stronger reservation than C18 to polar compound. Test shows that C8 can extract fat-soluable and water-soluable vitamin in human blood.
