Back Cover: A novel sensitive analytical method for the simultaneous analysis of vancomycin and teicoplanin in human urine via single HPLC coupled with Photodiode array and Mass Spectrometry in series

DOI: 10.1002/jssc.202200002 The cover picture shows a novel analytical protocol using single HPLC coupled with photodiode array and mass spectrometry in series, for the simultaneous determination of two glycopeptides with structural similarities: vancomycin and teicoplanin in human urine. According to the cover picture, for the treatment of the urine samples, a solid phase extraction protocol was developed and optimized, making the specific analytical method more sensitive and reliable for the simultaneous determination of these glycopeptides in difficult matrices such as urine samples.
