ABSTRACT The ionic strength of mobile phase can significantly affect the peak shape of ionogenic compounds such as antibiotics in reversedphase high performance liquid chromatography. The influence may be attributed to overloading of ionogenic analytes in lower ionic strength mobile phase.

在反相高效液相色谱过程中,流动相的离子强度可显著影响可解离的化合物如抗生素的色谱峰形,原因在于流动相的离子强度较低时,色谱填料的固定相易于过载,使离子化的化合物的色谱峰形呈典型的过载特征――峰形接近直角三角形。

ABSTRACT The ionic strength of mobile phase can significantly affect the peak shape of ionogenic compounds such as antibiotics in reversedphase high performance liquid chromatography. The influence may be attributed to overloading of ionogenic analytes in lower ionic strength mobile phase. In such phase, peak becomes increasingly rightangled triangle in shape with increasing sample load together with increasing peak width and tailing.

The heating ionizes the atoms, and when the atoms reach a few million degrees Kelvin, they emit X-rays.

加热将会使原子离子化。当原子达到几百刀开尔文摄氏度时,就会释放x射线。

Methods Streptomycin and dihydrostreptomycin were extracted from honey samples using a liquid extraction with a phosphate buffer followed by a solid-phase extraction based on weak cation-exchange columns. After sample preparation, the hydrophilic interaction chromatography was used to retain streptomycin and dihydrostreptomycin on the column for the separation of the analytes from endogenous compounds. The aminoglycosides were detected and quantified with electrospray ionization tandem mass spectrometry.

方法用磷酸盐缓冲溶液提取蜂蜜中的链霉素和双氢链霉素后,经弱阳离子交换柱进行固相萃取,样品制备后采用亲水作用色谱,使链霉素和双氢链霉素实现保留,从而与内源性物质达到分离,采用电喷雾离子化串联质谱法检测和定量。
