QuEChERS

QuEChERS tubes, bulk media, build your own media and tubes. Featuring CarbonX technology, United Science specializes in QuEChERS for all fruits and vegetables for pesticides analysis in food. CarbonX is a revolutionary engineered carbon specifically designed for sample preparation and analytical work. It replaces graphitized carbon black (GCB) in sample prep methods. In QuEChERS pesticide analysis, it offers benefits of high planar pesticide recovery, better baselines, and more matrix removal. QuEChERS technique is not limited to food safety applications. It can be used for sample preparation in all kinds of water, environmental, and pharmaceutical applications.

  • IMG_1472-(1) UNIVERSAL dSPE Tubes for All Matrices From: $160.00
    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.
