Diphasic dialysis extraction technique for clenbuterol determination in bovine retina by gas chromatography-mass spectrometry

Secondary Metabolites Approach to Study the Bio-Efficacy of Trichoderma asperellum Isolates in India

“…The Gas Chromatographic (GC)-Mass Spectrometric (MS) and Liquid Chromatographic (LC)-Mass Spectrometric (MS) methods are recent and extensively used techniques for the analysis of volatile and also antifungal compounds in biological systems (Namera et al, 1999;Ramos et al, 1999;Tarbin et al, 1999;Mohamed et al, 1999;Pichini et al, 1999). These methods have been involved different mechanisms or process such as extraction, separation, purification and characterization of any compounds.…”

Selection and Application of ssDNA Aptamers against Clenbuterol Hydrochloride Based on ssDNA Library Immobilized SELEX

“…Currently, instrumental analysis and immunoassays are the main analytical methods available for CLB detection. The instrumental analyses, including high-performance liquid chromatography (HPLC), 8 liquid chromatography mass spectrometry (LC-MS), 9 and gas chromatography mass spectrometry (GC-MS), 10 rely on expensive instruments, complicated sample treatment, and professional personnel operation. Immunoassays, such as enzyme-linked immunoassay (ELISA), 11 electrochemical immunoassay, 12 and fluorescence immunoassay, 13 have advantages of specificity, accuracy, and sensitivity.…”

Determination of phenylethanolamine A in animal hair, tissues and feeds by reversed phase liquid chromatography tandem mass spectrometry with QuEChERS

“…Although gas chromatography-mass spectrometry (GC-MS) [8][9][10][11] and liquid chromatography-mass spectrometry (LC-MS) [12][13][14][15][16][17] methods have been developed to identify beta-agonists in biological samples, there are little literatures on identification of phenylethanolamine A in animal tissues and feeds [7,18]. A LC-MS/MS method had been recently developed by Sun and Yan in swine muscle [7].…”
