The development prospect of chromatograph

The chromatograph includes a sample introduction system, a detection system, a recording and data processing system, a temperature control system, and a mobile phase control system, and is a device for chromatographic separation and analysis. Chromatographs are widely used in environmental analysis, food and beverage analysis, chemical analysis, etc. due to their characteristics of stability, sensitivity, versatility, and automation. At present, common chromatographs include gas chromatographs, liquid chromatographs, and gel chromatographs.

Currently, chromatographs are moving toward miniaturization, rapidity, high-throughput, multi-functionality, and Other instruments, and are showing new trends. Although supercritical fluid chromatography (SFC) has formed a good complement to chromatography and liquid chromatography, it is still relatively rare and it should be promoted as soon as possible for its commercialization and large-scale application.

In recent years, the liquid chromatograph has developed toward polarization, and preparative chromatography has grown toward large-scale and industrialization. However, the analytical liquid-phase has been developed toward portability and chip development. Meanwhile, multidimensional separation and liquid-liquid chromatography are also being emphasized by the industry. Becomes a new trend. At present, China's liquid chromatography equipment still has a gap with the international level in the field of technological level, and it has weaker market power in the high-end market. Therefore, it is imperative to increase scientific research strength, improve technological level, and then increase competitiveness in high-end fields.

Although the market share of capillary electrophoresis in the world is not large, because capillary electrophoresis has been widely used in proteomics, metabolomics, and traditional Chinese medicine fingerprinting, it will be used more widely in the future, and the market scale will continue to expand and become an industry. Development can not be ignored.

Ion chromatography instruments are gradually being developed in many fields, especially in the field of life sciences, and have achieved important applications. Miniaturization, capillary ion chromatography, and combination chromatography are particularly rapid because they are more adaptable to market demands. In terms of technology, microfluidic technology has become the focus of attention. Currently, it has been widely used in capillary electrophoresis, PCR and other instruments. With the continuous development of industry standards, future development will be more rapid and standardized.
