## Abstract A new method for the determination of anti‐diabetic drugs metformin and rosiglitazone based on the use of capillary electrophoresis with electrospray mass spectrometry was developed. The proposed method allowed their separation within 11 min by using 50 mM formic acid at +20 kV. Positiv

## Abstract In order to improve the sensitivity of CE‐ESI‐MS for the analysis of brain‐gut peptides, a solid‐phase extraction combined with field‐amplified sample injection was used for the pre‐concentration of the brain‐gut peptides. Compared with the conventional pressure injection method, the se
