LR-351 Fourier Transform infrared spectrometer is a new generation of infrared spectrometer products carefully and independently developed. It has the characteristics of simple operation and easy maintenance. Itis an indispensable spectral analysis instrument for materials science, biomedical-pharmaceutical, petrochemical, food safety and other industries. Since its listing, it has occupied a leading position in the domestic market and won the support and trust of the majority of users.
Experimental principle
Using the working principle of interferometer interference frequency modulation, the light emitted by the light source is changed into interference light through the Michelson interferometer, and then the interference light irradiates the sample, the receiver receives the interference light with the sample information, and then the spectral diagram of the sample can be obtained by the computer software through Fourier transform.
Advanced technology, the overall design is reasonable and stable
1. The interferometer adopts electromagnetic driven Michelson interferometer, which has continuous dynamic adjustment function without optical compensation. Automatic optimization of system energy without manual adjustment;
2. Sealed interferometer design, with automatic protection reminder device, more ergonomic principle and easy to observe, the instrument can replace the desiccant without opening the cover, easier maintenance.
3. Light source, beam splitter, detector and other core components are imported;
4. The gold-plated mirror with large aperture is used as the moving mirror and fixing mirror of the interferometer, which has excellent energy efficiency;
5. The off-axis mirror adopts SPDT cutting technology, which has excellent optical efficiency and system consistency;
6. The main components are installed by positioning the needle without adjustment, which greatly enhances the stability of the instrument and reduces the maintenance cost;
7. Push-pull sample bin door design greatly reduces the interference of water and carbon dioxide in the outside air to the experimental test results.
8.24-bit, 500KHz A/D conversion, high-speed USB2.0 interface, compatible with USB3.0 high-performance electronic system, to achieve real-time acquisition of spectral data, to ensure the authenticity and reliability of data;
9. Large sample bin design, convenient connection of various accessories, such as ATR accessories, diffuse reflection accessories, plane reflection accessories, gas pool, etc
10. Adopt efficient and energy-saving electrical system design, normal operation, the power consumption of the whole machine is less than 30W, green safety and energy saving;
11. The instrument design is compact and compact, the overall weight is only 14Kg, saving the space of the experiment platform;
Powerful operating software design
1. Intelligent human-computer interaction design, intuitive and simple system interface, no matter whether you have contact with Fourier infrared software, you can quickly get started and skilled operation;
2. Spectrum data acquisition preview of the whole monitoring mode, the acquisition process at a glance;
3. Can provide a variety of professional infrared spectrum library (about 220,000), covering a variety of industries, to meet the routine search, users can also customize the new spectrum library for search, flexible and convenient.
4. The operating software includes baseline correction, data conversion, multi-component quantification, curve peak fitting, H20/CO2 automatic compensation, absorbance transmittance conversion, KK conversion, peak marking, four operations, Y-axis normalization function, QC comparison, basic analysis and other functions; Support CSV,SPA,DPT,TXT and more than a dozen formats; Supports arbitrary switching of wave number cm-1 and wavelength um.
