Fourier Transform Infrared Spectrophotometer The IRAffinity-1S is a compact Fourier transform infrared spectrophotometer that is housed within an elegant form. The interferometer is continuously optimized by a dynamic alignment mechanism, and a built-in auto dryer helps ensure ease of maintenance. The IRAffinity-1S offers the high S/N ratio (30,000:1, 1-minute accumulation, neighborhood of 2,100 cm-1, peak-to-peak), a maximum resolution of 0.5 cm-1, and compact dimensions. Furthermore, the high-performance LabSolutions IR software, which emphasizes operability, and analysis support programs (Contaminant analysis program and Pharma Report program) make it easier to perform data processing and analysis. Highest S/N Ratio in Its Class: 30,000:1 Through the incorporation of a high-energy ceramic light source, a temperature-controlled, high-sensitivity DLATGS detector, a high-throughput optical element, and the optimization of the electrical system and optical system, the IRAffinity-1S achieves the highest S/N ratio in its class. Ease of Maintenance Ensured by Built-in Auto Dryer Beam splitters in the interferometers of FTIR instruments are susceptible to humidity. In order to maintain the long-term stability of the interferometer, the beam splitter must be protected. In the IRAffinity-1S, the interferometer is airtight and incorporates a unique internal auto dryer.
