Development of Raman spectrometer:
Raman spectrum analyzer is a very important analytical instrument that can be used to study the structure and chemical composition of materials. In the past few decades, this kind of analytical instrument has been continuously developed and has been widely used in many fields. Raman scattering used in Raman spectroscopy instruments was first proposed by the Indian physicist Raman in the 1920s, after which instruments began to be developed to use Raman scattering for analysis. In 1960, the advent of ruby lasers made Raman spectroscopy a new leap forward, and commercial Raman spectrometers began to develop rapidly. In the mid-1970s, Raman probes appeared and breathed life into microzone analysis. Since the 1980s, different types of Raman spectrometers have appeared one after another. However, the volume of instruments is large.
With the development of Raman spectroscopy technology, the design of Raman spectrometer is becoming more and more miniaturized, the portable Raman spectrometer came out at the end of 2015, and the handheld Raman spectrometer was successfully developed and entered the market in 2017. It realizes the role transformation from laboratory analytical instrument to portable application inspection equipment.
Classification of Raman spectrometer:
From the appearance of the Raman spectrometer, it can be divided into large scientific research Raman spectrometer, portable/handheld Raman spectrometer. Because the large Raman spectrometer is large in volume and form and accurate in detection, it is mainly used in the laboratories of scientific research institutes in universities to do scientific research. The portable/handheld small Raman spectrometer has a smaller appearance and is more used in first-line detection sites. The large Raman spectrometer is more precise than the portable/handheld Raman spectrometer, but it is less flexible and portable. Portable Raman spectrometer can be used in the field for rapid inspection and material screening work, with similar products unmatched simple operation and small and lightweight characteristics.
Applications of Raman spectrometer:
Raman spectrometer has attracted more and more attention because of its high sensitivity, high speed, no damage and high analysis efficiency. It has been paid more and more attention in the fields of safety inspection, food safety testing, customs inspection, public security field anti-drug, pharmaceutical raw materials, industrial online analysis, environmental monitoring, archaeological identification, gem identification and life science, and has a good market prospect.
It can be used for the identification of pesticide residues in food, agricultural and animal husbandry products. Non-destructive testing of explosives, drugs, ink, etc. is a powerful means to provide scientific evidence for the court; Used in chemical, polymer, pharmaceutical and medical processes for quality control, ingredient identification, drug identification, disease diagnosis; For the study of physical optics and semiconductor components; For water pollution monitoring, surface pollution detection and other organic pollutants; Used for nondestructive analysis of cultural relic samples. To make the methods of identification, dating and restoration and preservation of cultural relics safer and more reliable; Spectroscopic analysis of gemstones to understand the difference of inclusions in different gemstones. The identification and evaluation of gemstones have scientific basis. In addition, in recent years, Raman spectroscopy has also made great progress in the detection of cancer in cells and tissues, with the improvement of analytical methods, the increase of cases studied and the deepening of the regularity of differences in pathological tissues. The feasibility of developing Raman spectroscopy into a method for diagnosing tumors will be confirmed. In short, with the development of technology and the improvement of detection devices, Raman spectrometer has been more and more widely used in contemporary industrial production, article detection and scientific research.
Applications of Raman spectrometer Customer base:
Large Raman spectroscopy instruments are more used in university research institutes, especially physics, chemistry and materials colleges, in addition to third-party testing institutions and government full-time testing departments in the society. Portable/handheld Raman spectrometer is more used in the government food and drug ring detection department, rural agriculture department, food and drug market supervision and administration department, chemical and pharmaceutical enterprises, public security police stations and customs and other units customer group applications.
Raman spectrometer market application changes:
In the past few years, the market for large Raman spectral instruments has shown steady growth, and in the second half of 2022, sales have increased significantly under the influence of policy subsidies.
Portable/handheld Raman spectrometer performance growth of government units is mainly affected by policy, 2017-2019 market supervision Administration centralized procurement, since then the market of this part of the government department is very small, the public security department of rapid inspection laboratory construction is expected to continue until 2024, scientific research applications are mainly limited by funding.
