overview:

C8/SCX is the extraction column (C8/ SCX), which is composed of silica gel as matrix C8 and strong cation exchange SCX packing in combination with the optimized proportion, and provides dual retention mechanism. The C8 functional groups interact with the hydrophobic groups of the analyte, while the SCX has an interaction with the proton. Because of these strong interactions, stronger flushing conditions can be used to remove the common extracts that may interfere with UV detection or cause LC-MS ion suppression. There is no closure of the stationary phase, which can increase the interaction between the residual silyl alcohol base and the polar analyte, thus helping to enhance retention.

details：

Matrix：Silica
Functional Group：Octyl，Phenyl sulfonic acid
Mechanism of Action：Reverse phase extraction, strong Cation exchange
Particle Size： 40-75μm
Surface Area：510 m2 /g
Application: Soil;Water;Body fluids(plasma/urine etc.);Food;Oil
Typical applications: The functional groups of C8 / SCX are composed of octyl and sulfonic acid based on the ratio bond, which have a dual retention function:the octyl provides medium hydrophobic action, and sulfonic acid base provides strong cation exchange In the case of excessive adsorption of C18 and C8, as well as the strong retention of SCX, it can be used as the extraction column of C8 / SCX mixed mode

Typical Applications

The functional groups of C8 / SAX are composed of octyl and quaternary ammonium salts, which are combined byproportion and have a double retention function: octyl provides medium hydrophobic function and quaternary ammoniumprovides strong anion exchange In the case of excessive adsorption of C18 and C8, and the ability of SAX retention to be too strong, it can be used as the extraction column of C8 / SAX mixed mode
