Extraction in which samples are blended with an abrasive solid sorbent, forming a free flowing powder from which target analytes are recovered by solvent elution.
Notes:
- A typical workflow scheme for matrix–solid-phase dispersion is shown in the figure below.
- For additional sample clean-up the sorbent/sample mixture is deposited at the head of a solid-phase extraction cartridge containing a suitable sorbent to retard the elution of matrix components.
Typical work flow scheme for solid-phase matrix dispersion. (i) Sample is blended with an abrasive sorbent, (ii) free flowing powder containing sample is packed in a short column, and (iii) target analytes are recovered by elution.
