A new ionic liquids-based monolithic column for determination of caffeine and theophylline

The present study has concentrated on finding a new stationary phase in liquid chromatography. To improve the selectivity of monolithic column, a new ionic liquids-based (ILs-based) monolithic column (150 ? 4.6 mm i.d.) is synthesized.

Application of ultrasound‐assisted matrix solid‐phase dispersion extraction to the HPLC confirmatory determination of cephalosporin residues in milk

Ultrasound?assisted matrix solid?phase dispersion (MSPD) was applied to isolate eight cephalosporins (cefadroxil, cefaclor, cephalexin, cefotaxime, cefazolin, cefuroxime, cefoperazone and ceftiofur) from milk. Multi?residue analysis was subsequently performed by HPLC?diode array detection.
