Abstract

This paper reviews solid phase extraction as applied to the sample preparation of catecholamines and biologically active peptides. The mechanisms used in solidphase extraction are: nonโ€polar, polar, ionโ€exchange, and covalent.

## Abstract In the work, a rapid, simple and highโ€throughput sample preparation method was developed for the determination of sulfonamide (SA) antibiotic residues in chicken breast muscle. The extraction and cleanโ€up were online combined and up to 20 samples can be treated simultaneously in 6โ€‰min.
