my country's first "General Specification for Raman Spectrometers" was released

[ Policies and Regulations of Chemical Machinery Equipment Network ] Recently, the State Administration for Market Regulation and the National Standardization Administration approved the issuance of 386 recommended national standards and 3 national standard amendments
.
Among them, the "General Specification for Raman Spectrometers" (GB/T 40219-2021) will be implemented on December 1, 2021
.

 

Raman spectrometer is widely used
 

Raman spectrometer is mainly used in scientific research institutes, physics and chemistry laboratories of colleges and universities, biological and medical fields, and other optical aspects to determine and confirm the composition of research materials; it can also be used in criminal investigation and jewelry industry for the detection of toxic substances and gems Of identification
.
The instrument is known for its simple structure, easy operation, fast, efficient and accurate measurement, and is known for its low wavenumber measurement capability; it adopts a confocal optical path design to obtain higher resolution, and can perform um-level micro-area detection on the sample surface, and it can also be used for Microscopic image measurement
.

 

Standards first, norms guide
 

The national standard of "General Specification for Raman Spectrometers" stipulates the terms and definitions, classification, requirements, test methods, inspection rules, signs, packaging, transportation and storage of Raman spectrometers
.
The formulation of this standard will end the history of no Raman spectrometer standard in China, and standardize the production inspection standards of Raman spectrometer manufacturers, making the quality of products entering the market more secure
.

 

For the scientific instrument and analytical testing industry, the formulation, revision and implementation of relevant standards are of great value and significance to the market promotion of instrument technology and analytical methods
.
According to incomplete statistics (search with "Raman" as a keyword), there are currently 10 national standards related to Raman spectroscopy (2 of which will be implemented soon), 8 industry standards, and 4 local standards
.
On the one hand, the release of relevant instrument standards regulates the unified evaluation standards of Raman spectrometers, such as "General Specification for Raman Spectrometers" (GB/T 40219-2021), " Technical Requirements for Portable Raman Spectroscopy Rapid Detectors " (DB35/T 1564-2016), etc.
; on the other hand, with the exploration of the application direction, a series of related application standards have been released one after another, such as the "Raman Spectroscopy Method for the Measurement of the Number of Layers of Two-dimensional Materials Related to Nanotechnology Graphene" (GB/T 40069 -2021), etc.
; in addition, relevant group standards are also under construction, such as "Laser Raman Spectroscopy for Identification of Jewelry and Jade" (T∕CAQI 133-2020), "Laser Raman Jewelry and Jade Detector" (T/CIS17001-2016), as well as the jade identification group standard "Sample Identification of Jade" (T/GYSP 5—2018) that uses Raman spectroscopy as the main detection and analysis method, etc.

 

Relevant standards are still being improved
 

With the development and application of light source technology and nano-enhanced substrates, detection technology based on Raman spectroscopy has been widely used in qualitative and quantitative analysis in the fields of food safety, environmental science, public safety, and biomedicine, and has become a hot spot in the detection market
.
However, relative to the current application field of Raman spectrometer and the application direction that needs to be expanded in the future, the relevant standards are not enough
.

 

The formulation of this standard will end the history of no Raman spectrometer standard in China, and standardize the production inspection standards of Raman spectrometer manufacturers, making the quality of products entering the market more secure
.
This standard has reached an advanced level and will strongly promote the application of Raman spectroscopy technology and instrument development in China, thereby enhancing the development level and industry competitiveness of China's scientific instruments, and has significant scientific, economic and social benefits
