In recent years, various types of food safety and environmental pollution problems have become more and more frequent. Laboratory equipment and equipment, especially analytical instruments and related sample preparation and other product requirements have been increasing year by year. Government agencies and various analytical and testing organizations have analyzed the requirements of analytical test laboratories. Investment efforts have also gradually increased, and the equipment and equipment market has grown rapidly. According to the statistics of the China Instrument Industry Association, the sales revenue of analytical instruments at the back end of the chemical analysis process has increased year by year, and the auxiliary equipment used in conjunction with chemical analysis instruments has also shown a trend of rapid increase. Some laboratory equipment manufacturers have begun to focus on the autonomy of key technologies. R&D to improve the strength of China's equipment and equipment industry, especially in areas that have not been valued in the development of previous chemical analysis fields, such as sample pretreatment products and other laboratory general equipment (laboratory routine heating and cooling equipment) in a new round The performance in the growth is more prominent.

In a typical chemical analysis process, the sample preparation process takes more than 60% of the time. In addition, sample preparation is the main source of analysis error. As industry standards continue to rise, new sample preparation technologies are gradually becoming necessary prerequisites for improving the speed and accuracy of analysis results. Therefore, the domestic sample preparation technology has also entered new heights—especially the automation of sample preparation technologies. The trend is more and more obvious. The automation of sample preparation can bring many advantages, which can not only significantly reduce manual operation costs and human error, but also greatly reduce the risk of operator exposure to chemicals, and can also control the amount of chemicals and emissions such as solvents and strong acids. It will help reduce the risk of environmental pollution. In addition, a powerful software interface is another major advantage of automated sample preprocessing, allowing operators to graphically manage samples and flexibly set, save, and recall different pre-processing methods, making sample preparation easier. Therefore, in the past decade, automated sample preparation equipment not only has developed rapidly but also has expanded its market.

Driven by this industry background and the characteristics of the product itself, the analysis of the supporting sample pre-processing product industry also ushered in a new historical opportunity. Chemical analysis and related instruments marked by computer applications are undergoing new industry changes. Controlled analysis data acquisition enables continuous, rapid, real-time, and intelligent sample preparation and analysis. Analytical instruments and sample pre-processing products are moving in a new direction with higher sensitivity, higher accuracy, lower cost, more specialized, intelligent, automated, and easy-to-use interface. Some instrument manufacturers have begun to focus on the development of forward-looking technologies, and some products and technologies have reached the international advanced level.

There are numerous national sample pre-processing products and various analytical instrument manufacturers, and the market competition is fierce. In the future, it will develop along the direction of multidimensional advanced technologies, generally covering the following directions: (1) Integrate more products along the analysis and test process, improve product functions and (2) Summarize the design experience of laboratory automation products in the past decade in the country, improve the applicability of automation products and improve the user experience; (3) Promote the productization of new technologies, innovatively research and develop new products, and expand the existing market (4) Develop new laboratory equipment from the perspective of “green chemistry”. At present, typical products for automated sample preparation mainly include automatic solid-phase extraction systems, automatic GPC gel purification systems, automated concentration systems, and high-pressure solvent extraction systems in the field of organic analysis, and automatic electrothermal digestion devices in the inorganic field. And microwave digestion instrument.

According to the incomplete statistics on the domestic tendering and procurement markets, the market size of the above products is more than 800 million yuan. According to the average annual growth rate of 15% in recent years, the market capacity in this sector can double to 1.6 billion yuan in the next five years. The main driving force for the growth of products is the increase in the requirements for the construction of analytical test capabilities and the replacement of products brought about by the shift from manual operations to automated operations. The market capacity of the above major products is roughly as follows. The market size of fully automatic solid phase extraction system is approximately 30,000 yuan, the automatic GPC gel purification system is approximately 18 million yuan, and the high pressure solvent extraction system is approximately 35 million yuan. The market size of digestion instrument is about RMB 15,750 million, the market size of semi-automatic electrothermal digestion apparatus is about RMB 24 million, and the market size of automatic electrothermal digestion apparatus is about RMB 20 million. In the future, with the support of the national industrial policy and the increase of demand in the downstream industry, the market capacity of the above products will further increase.

In addition, the rapid development of analytical instruments and sample preparation products has driven the development of related laboratory equipment, such as the heating and cooling equipment commonly used in laboratory analysis activities. Taking the water circulation cooling thermostat as an example, it is estimated that the product market With a capacity of around RMB 200 million, the annual market demand is at least 20,000. With the continuous improvement of domestic laboratory construction standards and downstream user experience requirements, the technical level of such products has also improved significantly with the improvement of industry standards.

Cooling products mainly provide cryogenic temperature conditions for experiments or instruments. At present, the development of the product mainly presents the following trends: (1) High energy efficiency, high energy efficiency requires better heat transfer, heat exchange, and thermal isolation on the one hand, and reduces energy loss On the other hand, it requires product power specifications to be well matched to meet the needs of downstream users; (2) temperature controllability, common cooling equipment requirements temperature fluctuations within ± 1 °C range, high temperature performance instrument requires temperature control The range is within ±0.1°C and even lower. In addition, reasonable flow (as water) is required for open cooling. (3) Durability due to the fact that most compressors, Water pump and solenoid valve, all three are mechanical moving parts, so durability is an important basis and guarantee of product technology; (4) low noise, also due to mechanical moving parts, the noise in the cooling process needs to be well controlled. Do a good shock absorber design; (5) easy maintenance, heat exchanger surface, tanks, etc. must be easy to clean.

The heating products mainly provide high temperature and constant temperature for the experiment. The current technology trends are: (1) Safety, because the heating temperature is often higher than 60 °C, up to 450 °C, so the product design must consider the fire protection factor, and Fully prompt the user to prevent burns; (2) temperature controllability, on the one hand, the temperature fluctuations should be small enough, on the other hand, the process of temperature increase can be controlled by the program, that is, the program temperature; (3) temperature uniformity, due to heating Solid heat transfer, the uniformity of the surface temperature of the heater is very important, so as to avoid inconsistent heating effect in different locations, affecting the experimental results; (4) wide temperature range, heating temperature can be as high as 450 °C, so the heating body material (main properties are temperature resistance and Thermal conductivity is very critical; (5) Corrosion resistance. Strong acid and strong oxidants are often used in the laboratory where heating is required. This requires that the overall design of the product be resistant or chemically resistant. (6) Automation, especially for In experiments with high chemical exposure risks, automated design can significantly reduce the risk of chemical exposure, while at the same time increasing labor reproducibility relative to labor. .

With the support of national industrial policies, the increase in demand of downstream industries, and the improvement of industry standards, the market capacity and space for sample pre-processing and other laboratory equipment will further increase. In the future, the industry will usher in a new round of growth.
