The trend today is to use liquid chromatography tandem mass spectrometry, preceded with sample workup as liquid-liquid extraction or solid phase extraction.

Physical treatment techniques include, but not limited to, pump and treat, air sparging, and dual phase extraction.

Solid phase extraction can also be made on C18 sorbent cartridges.

These methods utilize solid phase extraction followed by high performance liquid chromatography.

This property can be useful in organic synthesis and separation methods such as solid phase extraction.

Analytical laboratories use solid phase extraction to concentrate and purify samples for analysis.

Solid phase extraction can be used to isolate analytes of interest from a wide variety of matrices, including urine, blood, water, beverages, soil, and animal tissue.

A typical solid phase extraction involves four basic steps.

Aqueous-two phase extractions do not require solvents, and so avoid these concerns.

It may refer to Liquid-liquid extraction, and Solid phase extraction.
