IRTracer-100 – the new Fourier Transform Infrared Spectrophotometer
for high-sensitivity, high-resolution and high-speed applications

Shimadzu, one of the world market leaders in spectroscopy, has introduced the IRTracer-100 Fourier Transform Infrared Spectrophotometer as a new milestone in infrared spectrometry.

The IRTracer-100 is a mid-range FTIR system that offers top performance, including the highest sensitivity levels in its class (S/N ratio of 60,000:1), high resolution (0.25 cm-1), and high measurement speed (20 high quality spectra per second in Rapid Scan mode).

Top performance means sophisticated FTIR analysis, such as highly sensitive measurement of micro contaminants, tracking measurements of rapid chemical reactions, or precise measurement of semiconductors or other materials. To ensure the high performance in combination with maximum stability, it also features an interferometer with advanced dynamic alignment and built-in dehumidifier and an instrument monitoring function.

Advanced Dynamic Alignment

Achieving reproducible optical interference in a spectrophotometer requires a robust interferometer design. The interferometer of the IRTracer-100 achieves this by incorporation of a “smooth moving” mirror system monitored by the patented Advanced Dynamic Alignment. This interferometer design provides optimum and stable quality spectra after only a short warm-up time. Sampling at over 5000 times /second, the Advanced Dynamic Alignment keeps IRTracer-100 in optimum operating condition. In addition, the Advanced Dynamic Alignment system automatically aligns the interferometer when the beam splitter is changed for NIR or FIR analysis.

Customized system configuration

The IRTracer-100 system is extremely flexible with a wide variety of accessories and easy-to-use software options that will meet the needs of each specific application. Measurements are possible from the near to the far infrared range. The large sample compartment allows an easy setup of accessories including the auto recognition. When the accessory is fixed in the sample compartment, its name and serial number are displayed on the software, and the optimum scan parameters are set.

Specifications are on a top level for both hardware and software. Using the IRTracer-100 in combination with the new LabSolutions IR software family makes it simple to fully utilize the high performance capabilities and enter sophisticated application areas. The LabSolutions IR software incorporates data processing functions such as advanced ATR correction and Kubelka-Munk conversion, quantitation functions such as the multi-point calibration curve method and the CLS method, as well as the spectral searching function as standard features. However, there is optional add-on software available for further increasing the application range with time course, PLS-quantitation, mapping, high-level macro-programming, and many more. For accurate identification of unknown samples, the LabSolutions IR software includes a library of 12,000 spectra.

High-speed monitoring

Some polymeric materials have a molecular structure that is altered due to treatments such as mixing, heating, light irradiation, and other. Some of these changes can take place within seconds, while others slowly progress over several hours.

A Fourier transform infrared spectrophotometer such as the IRTracer-100 is extremely effective for tracking chemical reactions and changes because measurements can be conducted very easily and at a high speed. The Rapid Scan feature allows the measurement of a curing reaction process that occurs in UV-curable resin.

A UV-curable resin such as acrylate can be hardened relatively quickly through the process of radical polymerization, which is accomplished by irradiating the material with ultraviolet light. Although the curing process proceeds relatively slowly if a typical indoor fluorescent light source is used, a powerful UV lamp provides much stronger ultraviolet irradiation, permitting to complete the curing process within seconds. In order to keep up with these very fast reactions, it is necessary to use an FTIR equipped with high-speed scanning capability. The Rapid Scan feature of the IRTracer-100 FTIR permits acquisition of 20 high-quality infrared spectra per second, enabling precise observation of the curing reaction process even when it is completed within a few seconds. More information about high-speed monitoring and additional applications is available for download.

System validation

The IRTracer-100 is equipped with a validation program that complies with the European, Japanese, Chinese, and U.S. Pharmacopoeias and with ASTM (American Society for Testing and Materials) specifications. The validation program checks the basic performance of the instrument using a polystyrene film, and creates reports of the results. If any failure was detected, the IRTracer-100 is adjusted and optimized using the Advance Dynamic Alignment mechanism.
