Mixed Mode Base SPE Column
Technical Specification
C8/SAX Octyl/Strong Anion Exchange | |
Extracting acidic drugs in biological fluids C8/SAX is composed of silica gel bounded with Octyl and quaternary ammonium groups at a specific ratio.It’s a mixed-mode sorbent with two retention mechanisms: octyl groups provide moderately hydrophobic interactions,quaternary ammonium groups provide strong anion exchange. - Moderate retention, avoiding extremely strong adsorption of some compounds |
Specifications 1.urface area: 480 m2 /g Applications - Determination of drugs and their metabolites |

C8/SCX Octyl/Strong Cation Exchange | |
Extracting basic drugs in biological fluids C8/SCX is composed of silica gel bounded with octyl and phenylsulfonic acid groups at a specific ratio. It’s a mixed-mode sorbent with two retention mechanisms: octyl groups provide moderately hydrophobic interactions, phenylsulfonic acid groups provide strong cation exchange. C8/SCX will be a better choice if very strong adsorption in C18, C8 or SCX packing results in difficult elution of some analytes. - Moderate retention, avoiding extremely strong adsorption of some compounds

GCB/NH2 Graphitized Carbon Black /Aminopropyl Bilayer | |
Cleanup of samples in multiresidual pesticide analysis Carbon-GCB/NH2 combines the merits of both Carbon-GCB and NH2 sorbents and is able to remove interfering compositions such as pigments, sterols and fatty acids in food samples, making it an effective packing for cleaning samples up in multiresidual pesticide analysis. - Ultrathin frits between two sorbent layers promising uniform flow Applications - Analysis of multiresidual pesticides in foods. |

GCB/PSA Graphitized Carbon Black/ Primary-Secondary Amine Bilayer | |
Cleanup of samples in multiresidual pesticide analysis Carbon- GCB/PSA is a sorbent similar to Carbon- GCB/NH2 and suitable for cleaning samples up in multiresidual pesticide analysis. Due to its additional secondary amino groups, PSA has higher ion exchange capability and ability to chelate some metal ions, thus providing Carbon-GCB/PSA with unique selectivity different from Carbon-GCB/NH . - Ultrathin frits between two sorbent layers promising uniform flow
