Analytical techniques for sedative drug residues-purification methods (3)

3) Solid phase microextraction (SPME)

SPME technology is a relatively new sample processing technology that can be used for online chromatographic analysis

Queiroz et al.

4) Liquid phase microextraction (LPME)

The LLE-based LPME technology overcomes many shortcomings of traditional LLE.

Ugland et al.

5) Molecular imprinting technique (MIT)

MIT is an imprinted polymer with high selectivity and recognition that artificially mimics antibodies by copolymerizing functional monomers combined with template molecules and cross-linking reagents

Ariffin and others used methacrylic acid and ethylene glycol dimethacrylate to prepare a molecularly imprinted polymer (MIP) of diazepam, which is used to extract and purify benzodiazepines in hair

6) Immunoaffinity solid phase microextraction (immunoaffinity solid phase microextraction)

The principle of immunoaffinity solid-phase microextraction is similar to that of SPME.

Lord et al.

7) QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe)

QuEChERS is a rapid sample pretreatment technology for agricultural product testing developed on the basis of MSPD technology

Usui et al.
