FSM Series Fourier-Transform Infrared Spectrometers

FSM Series Fourier-Transform Infrared Spectrometers

The Fourier-transform infrared (FT-IR) spectrometers - are laboratory spectrometers for mid-IR and near-IR regions. They are intended for qualitative and quantitative analysis of solid, liquid and gaseous samples and for quality control of products by IR spectra.

The spectrometers are fully automated and PC controlled.

The instruments are docketed into the State Register of Measuring Means (MM) of the Russian Federation, No. 18895-99. The certificate is validated in Ukraine, Republic of Belarus, and Republic of Kazakhstan.

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

Obtaining and registering the results of the measurements is completely automatic. A high effectiveness and reliability of data processing is ensured.

Easy of operation

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.

Applications of Fourier-transform IR spectrometry
