GS-Tek - Silica-Base Sorbents for SPE Cartridges

C18, C18-N, C8, NH2, COOH, Silica, PSA, PRS, SCX, SAX; All of them are made by high quality and pure silica particles. Using the special surface modification methodology, the activity of the silica surface is reduced largely, which in turn reduces the tailing of compounds and ensures high recovery and good reproducibility.
