Desorption electrospray ionization mass spectrometry (DESI-MS) is applied to the analysis of carbohydrates and steroids; the detection limits are significantly improved by the addition of low concentrations of salts to the spray solvent.
解吸电喷雾电离质谱法(DESI-MS)被应用于碳水化合物和类固醇的分析;通过向喷雾溶剂中添加低浓度盐,检测限得到显著提高。
