Copure QuEChERS includes extraction pouches and 50 mL centrifuge tubes, ceramic homogenizers are optional.
The pouches contain anhydrous extraction salts. Among the mixture, MgSO 4 is responsible for removing water in samples,while other components are responsible for maintaining appropriate pH to ensure the recoveries of alkaline-sensitive pesticides.
Directly adding water-abundant samples into tubes containing extraction salts may cause local overheating which compromise the resulting recoveries. To avoid such situations, separate extraction salt pouches are provided so that the operator can add extraction salts after the addition of organic solvents.
Copure QuEChERS salts are sealed in aluminum foil bags to avoid leakage. The type and amount are printed on the bag for easy selection. The easy-cut mark is very convenient for use.
