Spectrophotometer Executes Self-Diagnosis at Initialization

The IRAffinity-1 fourier transform infrared (FTIR) spectrophotometer from Shimadzu Scientific Instruments features high-throughput optics and a dynamic alignment mechanism to increase sensitivity, stability and usability. The spectrophotometer is suitable for high-precision infrared analysis to confirm, identify and detect foreign matter in raw materials, medical products, packages and coatings.

The spectrophotometer offers a signal-to-noise ratio of 30,000:1, with a maximum resolution of 0.5 cm^-1. The unit achieves this level of sensitivity by using a high-energy ceramic light source; temperature-controlled, high-sensitivity DLATGS detector; and high-throughput optical elements. Also, the spectrophotometer includes optimized electrical and optical systems to minimize noise levels.

The spectrophotometer includes technology to increase stability and precision. Its moving mirror is run smoothly and precisely by a proprietary flexible joint system. The interferometer is optimized and stabilized by a proprietary dynamic alignment mechanism. Its optical elements are protected from humidity and stabilized by a sealed interferometer, continuously removing moisture by a reactive polymeric desiccator and coating the beam splitter with moisture-resistant protective film.

To increase reliability, the spectrophotometer executes self-diagnosis at initialization and monitors the state of the instrument during operation. Users can check basic performance using a standard-feature validation program.

IRsolution software, standard in the spectrophotometer, emphasizes operability and analysis support programs to perform data processing and analysis. With specialized windows, users can easily perform standard operations, such as measurement, display, data processing, quantitative analysis, search and printing. A variety of optional programs and accessories, such as those facilitating PLS and multilinear regression, deconvolution, and mapping measurement, are also available.
