Abstract
It is an object of the invention to improve the current QuEChERS technology. In one aspect of the invention, the buffer-salt powder mixture of the first stage of the QuEChERS process is compressed into a solid dosage form before it is used in the first stage of the QuEChERS process. Replacing the QuEChERS powders (the buffer-salt powder mixture of the first stage of the QuEChERS process) with solid aliquots eliminates the need for using centrifuge tubes for packaging the product.
