It has all the advantages of the spectral NIR-analysis method: highly informative data obtained, high rate and accuracy of measurements, it does not require preliminary sample preparation and special training of personnel.
ФСМ 2211
FSM 2211 spectrometers are based on a Michelson-type interferometer, with self-compensation, which does not require dynamic alignment.

The creation of affordable industrial equipment and the combination of NIR spectroscopy method with a chemometric system for results processing in a short time has made this method extremely popular in areas such as the food products, drugs, perfumes and cosmetics. The simplicity, fast execution of analysis and the objectivity of the results provide the leading position of this method in the incoming quality control of raw materials, in the production process to control its critical points and finished products. The method is recommended, in particular, for revelation of counterfeit drugs.
This is done using a calibration model, which is a relationship between the absorption (transmittance) coefficient and the component concentration (sample property). The calibration model is calculated in advance using the results of the calibration, which consists in registration of the spectra of a batch of samples with known (established by standard chemical methods) concentrations of components or other known properties.
The location of the bands in the infrared absorption spectrum includes the information about the qualitative composition of the sample, while the intensity of the bands allows its quantitative analysis, i.e. determine the concentration (or other property) of the respective component.
Primary advantages of Fourier-transform IR spectrometers
  • High sensitivity
    FSM spectrometers significantly surpass dispersive spectrometers in sensitivity, which allows detection of extremely low concentrations and trace amounts of materials.
  • Rapidity
    Spectrum obtaining time is considerably reduced, which provides a high-speed measuring capability, complete product inspection capability, and a capability of real-time controlling of fabrication process parameters.
  • Automation of measurements. Easy of operation.
    Obtaining and registering the results of the measurements is completely automatic. A high effectiveness and reliability of data processing is ensured.
    The spectrometer requires no tuning, has the built-in wavelength standard; its testing procedure is automated.
  • Modular design.
    The spectrometer can be adapted to special applications: gas analysis, fuel and oil analysis, control of semiconductor silicon.
  • Software.
    The basic software operates under Windows 9х/ХР, and provides spectra measurement, spectrometer testing, and work with the spectra data base. There is a large set of operations intended for spectra processing, analysis and display.
