FTIR-990AD FT-IR Spectrometer
Principle
The FTIR with Michelson interferometer principle, the light emitted by the light source by Michelson interferometer to optical interference, let interference illumination samples, the receiver receives the interference light with sample information, and then by the computer software by transform to obtain the spectra of the samples.

Reliable optical system
Ø The design integrates main components to an optical bench machined from a cast aluminum, accessories will be mounted by needle positioning, no need to adjust.
Ø Sealed Michelson interferometer, combined with moisture proof beam splitter and bigger Moisture proof agent box to get 5 times moisture proof ability.
Ø The temperature observation window adopts 7 degree forward design, which conforms to the principle of human engineering, easy to observe and convenient to replace the molecular sieve.
Ø The design of push pull type sample bin can greatly reduce the interference of water and carbon dioxide in the air on the test results, and it’s designed larger to access various accessories.
Ø Working power less than 30W, green environmental protection。
High stable components
Ø The sealing interferometer uses USA imported gold cube corner reflector with high reflectivity and angular accuracy.
Ø With high performance long life ceramic light source imported from USA, the luminous efficiency is as high as 80%.
Ø VCSEL laser imported from USA with high performance.
Ø High sensitive DLATGS detector imported from USA.
Ø It’s off axis mirror using SPDT cutting process, with excellent optical efficiency and system consistency.
Ø The imported special steel rail, heavy load, low friction, ensure data stability and repeatability.
Powerful intelligent software
Ø Intelligent human-computer interaction and operation guide design, you can quickly get started and skilled whether you have contacted the FTIR software.
Ø Unique spectral data acquisition monitoring preview mode, land acquisition process.
Ø Provide standard library of approximately 1800 spectra for free, include most common Compounds, drugs, oxides.
We also can provide a variety of professional infrared Atlas (220000 pieces), covering a variety of industries, to meet the general retrieval, users can customize the new spectral database retrieval, flexible and convenient. The fingerprint library includes: the national pharmacopoeia library, National Veterinary Pharmacopoeia library, rubber library, gas spectrum Gallery, molecular spectrum Gallery, protein and amino acid spectrum library, judicial Library (dangerous goods, chemicals, pharmaceuticals etc.), inorganic organic spectral library, library, solvent spectrum library, library of food additives flavor library, paint, library etc(As appendix).
Ø Software with GB / T 21186-2007 national standard calibration function and JJF 1319-2011 infrared calibration standard calibration function.
