摘要
目前国内在线色谱仪使用中的最大问题还是在取样和样品预处理上,尤其是高温高压、宽沸程、组成复杂和需特殊处理的样品。因此研究更新采样方法和分析技术,发展适用性强、应用范围宽、高灵敏度、快速、成本低和易于维护的专用/多用在线色谱分析系统,以满足不同工业在线分析的要求和实验室研究的需要,将是在线色谱分析的发展方向之一。
At present, the biggest ing, especially the samples which need special treatment. To study problems in the use in high temperature of online chromatograph and high pressure ,wide- were sampling and sample preprocessboiling range, complex composition and special purpose or multi-purpose online chromatography system which has updated sampling methods and analysis techniques, development of applicability, wide range of applications, high sensitivity, fast,low cost and easy to maintain to meet the needs of different industrial online analysis of requirements and laboratory research needs, will be the development direction of online chromatographic analysis.
