SOLID ALIQUOTS OF MULTIRESIDUE METHOD SALTS FOR SOLID PHASE EXTRACTION APPLICATIONS

摘要

The purpose of the present invention is improve current QuEChERS technologies. In one aspect of the invention, the first order QuEChERS methods of solid dosage forms are compressed into before the first order QuEChERS methods use of buffer salt mixture of powders. Substitution QuEChERS powder (first stage of buffer salt mixture of powders QuEChERS techniques) and solid equal portions eliminate using centrifuge tube the needs for packing product.
