    UNIVERSAL dSPE Tubes for All Matrices

    UNIVERSAL dSPE Tubes for All Matrices

    0 out of 5

    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.
