dispersive SPE

Dispersive solid phase extraction tubes come in many different standard configurations for your every extraction need. Centrifuge tubes are free from contamination are filled with ultra clean sorbents for superior cleanup performance and baselines. Sorbents include alumina, C18, PSA, Primary Amine, and CarbonX. Dispersive tubes are typically used to remove the matrix and leave the analyte in solution.

  • IMG_1472-(1) UNIVERSAL dSPE Tubes for All Matrices From: $141.00
    Select

    This is dSPE tube is configured to remove matrix for multi-residue analysis. These UNIVERSAL dSPE tubes are configured with 50 mg of CarbonX, 50 mg of C18, magnesium sulphate; and PSA (primary-secondary amine SPE sorbent). Since CarbonX removes matrix and does not remove the pesticides, we recommend CarbonX addition to all QuEChERS tubes for all matrices- even for non pigmented samples. The kit consists of 2 mL (100 units) or 15 mL (50 units) centrifuge tubes.


  • IMG_1472-(1) UNIVERSAL dSPE Tubes with LipidX and CarbonX for Lipid Rich Matrices From: $141.00
    Select

    This is dSPE tube is configured with both CarbonX and LipidX for high lipid matrices for multi-residue analysis. These UNIVERSAL dSPE tubes are configured with CarbonX, LipidX, C18, magnesium sulphate; and PSA (primary-secondary amine SPE sorbent). Since CarbonX and LipidX removes matrix and does not remove the pesticides, we recommend these unique sorbents as a logical addition to all QuEChERS tubes for all matrices- even for non pigmented samples. The kit consists of 2 mL (100 units) or 15 mL (50 units) centrifuge tubes.
