Professional Supplier of Laboratory Scientific Instruments
The FTIR-20 Fourier Transform Infrared Spectrometer has the characteristics of easy installation, simple use and convenient maintenance. It is an indispensable spectral analysis instrument in the materials science, biomedicine, petrochemical, food safety and other industries. It is also a necessary laboratory analysis instrument for related majors in universities, research institutes and other related majors.
Using the working principle of interferometer frequency modulation, the light emitted by the light source is converted into interference light by the Michelson interferometer, and then the interference light is irradiated on the sample. The receiver receives the interference light with sample information, and then the computer software obtains the spectrum of the sample through Fourier transformation.
1. The interferometer uses a DSP-controlled electromagnetically driven non-orthogonal Michelson interferometer with continuous dynamic adjustment function, automatically optimizing system energy without manual adjustment.
2. Adopting three-dimensional right-angle gold-plated reflector optical compensation technology, the fixed mirror is constant and motionless, no mechanical dynamic adjustment is required, and the optical path is permanently aligned.
3. SuperTech digital technology electronic system. Fully digital, output digital signal. 24-bit, 500KHz A/D conversion, high-speed USB interface, to achieve real-time collection of spectral data, ensuring the authenticity and reliability of the data.
4. Silicon carbide rod infrared light source with electronic voltage-stabilized power supply technology, using 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 film.
6. KBr substrate multilayer germanium-plated beam splitter, and optional beam splitters made of various reliable moisture-proof materials such as ZnSe and KRS-5.
7. The instrument has a built-in industrial-grade temperature and humidity display screen, which directly digitizes and displays the internal temperature, humidity and humidity alarm value of the instrument in real time. When the humidity alarm value is reached inside the instrument, a buzzer alarm is issued to prevent the core components of the instrument from being damaged due to deliquescence.
8. The windows, detectors, and beam splitters are coated with special coatings, which have ultra-high transmittance and can also reduce the corrosion of potassium bromide by moisture.
9. Excellent optical mirror design: The optical reflector adopts the overall SPDT cutting process to ensure the high reflection efficiency of the mirror and the consistency of the optical system.
10. The expansion function is powerful, and can be connected to transmission accessories, attenuated total reflection accessories (ATR accessories), diffuse reflection accessories, plane reflection accessories, in-situ accessories, etc.
11. Intelligent human-computer interaction operation guidance design, whether you have been exposed to Fourier infrared software or not, you can operate quickly and use it proficiently.
12. Spectrum library: It can provide a variety of professional infrared spectrum libraries (about 220,000), covering various industries. In addition to meeting conventional searches, users can also customize new spectrum libraries for retrieval, which is flexible and convenient. The spectrum library includes: National Pharmacopoeia spectrum library, National Veterinary Pharmacopoeia spectrum library, rubber spectrum library, gas spectrum library, polymer spectrum library, protein and amino acid spectrum library, judicial spectrum library (hazardous goods, chemicals, drugs, etc.), inorganic spectrum library, organic spectrum library, solvent spectrum library, food additive spectrum library, flavor and fragrance spectrum library, coating spectrum library, etc.

Qualitative analysis is often used for the overall identification of substances. For samples that can be anticipated in advance, the identification can be confirmed by comparing the sample infrared spectrum with the standard infrared spectrum. For samples that cannot be anticipated in advance, identification can be performed by searching the infrared spectrum library. Our company can provide about 220,000 Sadtler spectra.
