Erythromycin electrochemical detection

Electrochemical detection is better suited to the analysis of erythromycin and lincomycin. This method of detection has been applied for the determination of erythromycin A (139) and lincomycin (154) residues in salmon tissues. Liquid chromatography coupled with mass spectrometry is particularly suitable for confirmatory analysis of the nonvolatile macrolides and lincosamides. Typical applications of this technique are through thermospray mass spectrometry, which has been used to monitor pirlimycin in bovine milk and liver (141,142), and chemical ionization, which has been applied for identification of tilmicosin (151) in bovine muscle, and for identification of spiramycin, tylosin, tilmicosin, erythromycin, and josamycin residues in the same tissue (150).

It is noteworthy that Ru(bpy)3 immobilization on the electrode surface facilitates the enhancement in the ECL intensity [134]. Ru(bpy)3 immobilized on an electrode surface comprising sol-gel-derived titania, and Nation was used for the determination of erythromycin in human urine sample. ECL combined with bipolar electrochemistry has been used for various analytical purposes by Crooks [66, 135-137] and Manz s co-workers [17]. Manz employed ECL with bipolar electrode for the detection of amines and Crooks and co-workers for the detection of FefCN) , Ru(NH3)i, benzyl viologen, and various ananlytes. Recently, bipolar electrochemistry has also been coupled to ECL in order to propel light-emitting bipolar electrochemical swimmers Fig. 5.22. In this approach, synergestic action... [Pg.97]
