Text
Spectrum analyzer is an instrument used to measure the interaction between substances and electromagnetic radiation. It can be used to analyze the emission spectrum, absorption spectrum and scattering spectrum of substances. Its history can be traced back to the early 19th century, with the continuous progress of science and technology, the spectrometer from the initial simple equipment gradually evolved into a high-precision modern instrument.
Historical evolution
The History of spectroscopy dates back to the 17th century, when physicist Newton experimented with the dispersion of light, splitting sunlight through a prism into different colors of light. However, the development of modern spectrometers did not begin until the 20th century, when technology made great strides. In the 1960 s, China's large-scale optical instrument factory was born,It has achieved a breakthrough in the development and manufacture of optical analysis commodity instruments from scratch in China.
Working principle
The working principle of the spectrum analyzer is based on the principle of optical dispersion, which separates the polychromatic light emitted by the light source according to different wavelengths, and measures the spectral line intensity with various photoelectric detectors. Specifically, the spectrometer generally consists of a light splitting system, a receiving system and a data processing system. When the light from the light source passes through the sample,The atoms or molecules in the sample will absorb light of a specific wavelength, resulting in the degree to which the emission spectrum is weakened, so that the content of the element to be measured in the sample can be obtained. This process conforms to the Langper-Beer law (A = -lg I/Io = -LgT = KCL), where I is the transmitted light intensity, Io is the emitted light intensity,T is the transmittance.
In addition, the spectrometer can also use the dispersive component of the splitting effect, through different optical path forms, the complex light is decomposed into a series of independent monochromatic light, and then measured and calculated. For example, a Fourier Transform Infrared Spectrometer (FTIR) is an infrared spectrometer developed based on the principle of Fourier transforming interfered infrared light.
The main role
The main functions of the spectrum analyzer include substance identification and chemical analysis. By analyzing the absorption, emission, and scattering spectra of the sample, the composition and structure of the material can be determined. This technology is widely used in air pollution, water pollution, material identification and other fields. For example, it is widely used in scientific research and material analysis and will play a more important role in the future.
Industry background
Spectrum analyzer belongs to the high-end analytical instrument industry, which plays an important role in scientific research, production, quality control and other aspects, especially in the fields of automobile, semiconductor, new energy and so on. Among them, technological progress has become an important factor driving the growth of the spectrometer market.
Field of application
Environmental monitoring
Spectrum analyzer plays an important role in environmental monitoring and can be used to detect heavy metal elements in surface water and wastewater. Handheld molecular spectrum analyzer can also be used for the detection of atmospheric and water pollutants.
Chemistry and Materials Science
In the fields of chemistry and materials science, spectral analyzers can be used for the analysis of the composition of substances. For example, ICP spectrometer (ICP-AES/OES) is mainly used for the analysis of trace/trace elements, and is widely used in rare earths, precious metals, alloy materials, electronic products, medicine and other fields.
Biological medical treatment
Spectrum analyzers are also widely used in the biomedical field, such as disease diagnosis, pathogen identification and biological screening. Near infrared spectroscopy has been widely used in food quality control, agricultural chemicals analysis, pharmaceutical manufacturing and other fields because of its advantages of simple sample preparation and online analysis.
Food Safety
In the field of food safety, spectral analyzers can be used to detect calcium, magnesium and other elements and contaminants in food. Handheld molecular spectroscopy analyzers are also commonly used for food safety testing.
Commercial manufacture
Spectrum analyzer plays an important role in production process control and finished product inspection in metallurgy, casting, machinery, metal processing, automobile manufacturing, nonferrous metals, aerospace, chemical industry and other fields. For example, direct-reading spectrometers are widely used for quality control objectives in these industries.
Other Applications
In addition, the spectrum analyzer is also used in astronomical observation, printing, papermaking, gem composition detection and other fields. For example, spectroscopic instruments of the Fourier transform infrared (FTIR) or Raman scattering type are widely used in chemistry, materials science, and other industries that require precise analysis of optical properties.
