Lida-20 Fourier transform infrared spectrometer Introduction
Lida-20 has the characteristics of convenient installation, simple use and convenient maintenance. It can be widely used in many fields such as biomedicine, materials science, petrochemical, food safety, environmental protection, etc. It is an indispensable spectral analysis instrument for production and scientific research.
Lida-20 Fourier transform infrared spectrometer is the working principle of interferometer interferometry. The light emitted by the light source is converted into interference light by Michelson interferometer, and then the interference light is irradiated to the sample. The receiver receives the interference light with sample information. The spectrum of the sample can be obtained by Fourier transform from computer software. Features
Intelligent operating software
1.Intelligent human-computer interaction design, whether you have been exposed to Fourier infrared software, can quickly and proficiently operate;
2.The laser frequency correction mode can be selected, whether it is a national standard or a metrology specification;
3.Unique data acquisition preview full-process monitoring mode, the collection process is unobstructed;
4.With a variety of professional infrared map libraries, in addition to the regular search, users can customize the new library, you can add maintenance. The library includes: National Pharmacopoeia Library, National Veterinary Pharmacopoeia Library, Rubber Spectrum Gallery, Gas Spectrum Gallery, Polymer Library, Protein and Amino Acid Library, Judicial Spectrum Gallery (Dangerous Goods, Chemicals, Pharmaceuticals, etc.), Inorganic Spectrum Gallery, Organic Spectrum Gallery, Solvent Spectrum Gallery, Food Additive Library, Fragrance and Fragrance Gallery, Paint Spectrum Gallery, etc.
Reliable optical system
5.Reliable sealed interferometer design, using a beam splitter with moisture-proof membrane and a large-capacity reusable desiccant cartridge to achieve 5 times moisture resistance of similar products. Visible color window for easy viewing and replacement of molecular sieves.
