China Ftir Fourier Transform Infrared Laboratory Spectrometer
Instrument introduction
It has the characteristics of convenient installation, simple use, and convenient maintenance. It is an indispensable spectral analysis instrument in the fields of material science, biomedicine, petrochemical, food safety, and other industries. At the same time, it is also a necessary laboratory analysis instrument for colleges and universities, research institutes, and other institutions. Since its listing, it has occupied the leading position in the domestic market and won the support and trust of the majority of users.
Working principle
Using the working principle of interferometer interference frequency modulation, the light emitted by the light source is converted 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 spectrum of the sample can be obtained through Fourier transform by computer software.
Instrument features
1. The interferometer uses DSP to control the electromagnetic drive Michelson interferometer, which has continuous dynamic adjustment function, automatically optimizes the system energy, without manual adjustment.
2. The optical compensation technology of three-dimensional right-angle gold-plated mirror is adopted, and the fixed mirror is constant without mechanical dynamic adjustment, and the optical path is permanently collimated.
3. The electronic system of SuperTech digital technology. Fully digital, output digital signal. 24-bit, 500KHz A/D conversion, high-speed USB interface, real-time spectral data acquisition, ensuring the authenticity and reliability of the data.
4. Silicon carbide rod infrared light source with electronic voltage stabilizing power supply technology adopts digital power supply technology to provide stable and reliable power supply support for the light source and ensure that the light source has an ultra-long service life.
5. High sensitivity DLATGS receiver with polymer moisture-proof membrane.
6. KBr substrate multi-layer germanium plated beam splitter, and other reliable moisture-proof materials such as ZnSe and KRS-5 can be selected.
7. The instrument is equipped with an industrial temperature and humidity display screen, which can directly display the internal temperature and humidity and humidity alarm value of the instrument in digital real-time. When the internal humidity alarm value is reached, a beep alarm will be sent to prevent the core components of the instrument from being damaged due to deliquescence.
8. The window, detector and beam splitter are coated with special coating, which has ultra-high transmittance and can also reduce the corrosion of moisture to potassium bromide.
9. Excellent optical mirror design: the optical mirror adopts the overall SPDT cutting process to ensure the high reflection efficiency of the mirror and the consistency of the optical system.
10. With powerful expansion function, it can connect transmission accessories, attenuated total reflection accessories (ATR accessories), diffuse reflection accessories, plane reflection accessories, original
Accessories, etc.
11. Intelligent human-computer interactive operation guidance design, whether you have contact with Fourier infrared software or not, you can quickly operate and skillfully use it.
12. Spectrum library: It can provide a variety of professional infrared spectrum libraries (about 220000), covering various industries and meeting the requirements of conventional retrieval, users can also User-defined new spectrum library for retrieval, flexible and convenient. The atlas library includes: national pharmacopoeia atlas library, national veterinary pharmacopoeia atlas library, rubber atlas Graph library, gas graph library, polymer graph library, protein and amino acid graph library, judicial graph library (dangerous goods, chemicals, drugs,etc.) inorganic spectrum library, organic spectrum library, solvent spectrum library, food additive spectrum library, essence flavor spectrum library, paint spectrum Library, etc.
