Mixed Mode Base SPE Column

Column capacities consist of 1, 3, 6, and 10 ml sizes, etc.

Our manufacturing process minimizes variability and improves recovery and cleanup procedures

1.C8/SAX Octyl/Strong Anion Exchange

2.C8/SCX Octyl/Strong Cation Exchange

3.GCB/NH2 Graphitized Carbon Black/Aminopropyl Bilayer

4.GCB/PSA Graphitized Carbon Black/ Primary-Secondary Amine Bilayer

    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.
    C8/SAX will be a better choice if very strong adsorption in C18, C8 or SAX packing results in difficult elution of some analytes.

    - Moderate retention, avoiding extremely strong adsorption of some compounds
    -  Ideal for complicated samples such as blood and urine

    Specifications

    1.urface area: 480 m2 /g
    2.Particle size: 40 - 75 µm
    3.Pore size: 70 Å

    Applications

    - Determination of drugs and their metabolites
    - In biological fluids, such as barbiturates
    - Determination of drugs of abuse such as THC

    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
    - Capable of removing interferences as thoroughly as possible

    Applications

    - Analysis of multiresidual pesticides in foods.

    Specifications for GCB

    1.Surface area: 100 m2 /g
    2.Particle size:100-300 mesh

    Specifications for NH2

    1.Carbon content: 4.5%       2.Surface area: 480 m2 /g
    3.Particle size: 40-75 µm       4.Pore size: 70 Å

    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
    - Capable of removing interferences as thoroughly as possible
    - Higher capabilities than Carb- GCB/NH 2

    1.Surface area: 100 m2 /g
    2.Particle size:100-300 mesh

    Specifications for PSA

    3.Particle size: 50 - 75 µm       4.Pore size: 70 Å

    Applications

    - Analysis of multiresidual pesticides in foods
    - Determination of residual neonicotinoid pesticides in soil, fruit and wine samples
