However, there is disadvantages in the current MS method for the detection of compound A. For example, there are methods to measure the amount of A, but no structural information (物质结构定性) could be obtained. Also, there are screening processes to analyze multi-types of antibiotic (多种抗生素进行筛查), but none of them can quantify the A compound.
Based on the physical and chemical properties of A and the characteristic of HILIC column, our group decided to optimize the pH of the mobile phase under an acidic condition (酸性的范围).
I have analyzed the literature precedents (文献中的研究内容). Since there is difference between aims of this current study and those have been reported, which were mostly focused on the screening processes for multi-types of antibiotics, the analysis and comparison (比较说明) of the literature precedents has been included in the introduction section (前言部分). |
