Talking about the Future Development of Analytical Instruments

Analytical instruments As the industries that have developed in recent years, everyone will have a lot of speculations about their future development. The following are some of the characteristics of the development trends of analytical instruments summarized by Xiao Bian. They are for reference only.

1. The era of miniaturization and intelligent online analytical instruments is approaching With the development of high technologies such as computer technology, micromanufacturing technology, nanotechnology and new functional materials, analytical instruments will not only have more and more powerful “intelligence”, but also Moves in the direction of large-scale floor-to-desktop-mobile-portable-handheld-chip-labs, becoming more and more compact, miniaturized, intelligent, and even wearable or even externally implantable. Or embedded intelligent instruments. It is because computer technology is undergoing tremendous changes. With the constant launch of molecular computers, DNA computers, photonic computers, quantum computers, etc., computers will also be increasingly miniaturized. The boundaries between analytical instruments and special-purpose computers will also become blurred. Many analytical instruments are actually computers that have some sort of analytical detection capability.

2. Digitalization and Bionics In the late 1980s, with the rapid development of computer technology, the digitization of analytical instruments and the development of chemometrics were promoted, and chemometrics methods were used to solve spectral information extraction and background interference. The effect, combined with the unique characteristics of near-infrared spectroscopy in the sample-taking technology, has led people to re-recognize the value of near-infrared spectroscopy. The application of near-infrared spectroscopy in various fields has begun. In addition, the core of the analytical instrument is signal sensing. For example, chemical sensors have gradually developed into miniaturization, biomimetics, such as biochips, chemical and physical chips, olfactory (electronic nose), taste (electronic tongue), freshness, and food detection sensors. Biosensors are widely used in various fields such as medicine, clinical, biology, chemistry, environment, agriculture, industry, and even robot manufacturing. There are roughly five types of biosensors: enzyme sensors, tissue sensors, microbial sensors, immunosensors, and field-effect (FET) biosensors. Its principle is based on the composition of the electrochemical, optical, thermal and other. The probe consists of two main parts. The first is a "receptor" made of a membrane with a highly selective molecular recognition ability for the substance to be measured (substrate); the other is the consumption of a biochemical reaction on the membrane. The resulting chemical or generated light and heat is converted into a "transducer" of the electrical signal. The resulting signal is electronically processed and can be displayed and recorded on the instrument.

3. Specialization and automation With the development of environmental science, to control and control environmental pollution, prevent environmental degradation and maintain ecological balance, environmental monitoring has become an important means to grasp the state of environmental quality, and development of chemical poisons, noise, electromagnetic waves, bionics Special-purpose analytical instruments for monitoring sexual and heat pollution have received more and more attention. She can be used to monitor pollution sites in real time, conduct fixed-point and regular monitoring of the human living environment, and remotely monitor pollution sources. Conventional analytical instruments are bulky, complex in structure, and consume large amounts of energy, which keeps the cost of normal operation of the instrument high. Now with the development of new materials, new devices, and microelectronics technologies, instrumentation has been miniaturized, with excellent performance-to-price ratio, and with a high degree of automation.

4. Applications are expanding In the early years of the 20th century, the classic analytical techniques and analytical instruments were mainly used for modern industrial production, mainly to adapt to analysis, monitor industrial and agricultural production, ensure product quality, and ensure the safety and efficiency of large production processes. Requirement to develop and improve; at the turn of the century, the "useful place" of analytical techniques and analytical instruments has been greatly expanded, and the most striking ones are the applications in the fields of biology, environmental protection, medicine, and other related people's survival and development. The development of high technology in the military has also promoted the application of analytical techniques and analytical instruments. (For example, high-speed, sensitive and accurate on-site poison detection in biological weapons and chemical weapons warfare, life support tasks have also greatly expanded the application of analytical instruments.) . It can be seen that after the arrival of the new century, the application of analytical techniques and analytical instruments will be more pronounced from the "material" to "human" trend.

Xiao Bian thinks that we must look to analyze the trend of development, in the analysis of the development of the cause of the instrument in the right position, choose a good direction, in order to long-term development of analytical instrument industry.
