The IRAffinity-1 offers the highest S/N ratio in its class* (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 IRsolution software, which emphasizes operability, and analysis support programs (a foreign matter analysis program and a Japanese Pharmacopoeia compliance program) make it easier to perform data processing and analysis.
*As of January 2008, according to Shimadzu investigations.
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-1 achieves the highest S/N ratio in its class.
Ease of Maintenance Ensured by Built-in Desiccator (JPN:registration of utility model No.3116465)
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-1, the interferometer is airtight and incorporates a unique internal desiccator (JPN:registration of utility model No.3116465).
Equipped with Analysis Support Programs
The two main applications of infrared analysis are the analysis of foreign matter and identification tests. At Shimadzu, in order to allow operators with little experience in infrared analysis to fully utilize the functionality of the IRAffinity-1, we have prepared analysis support programs. These programs are useful in a variety of analysis scenarios where infrared spectra are used.
Contaminant Analysis program (Patent pending)
By combining a library of spectra for substances that are often detected as foreign matter and Shimadzu's own algorithms, this program identifies foreign matter with a high degree of accuracy. Reports are automatically created after analysis, so operators with little knowledge of infrared analysis can perform analysis easily.
This program contains spectra for over 300 highly-selected inorganic substances, organic substances, and polymers that are often detected as foreign matter in Shimadzu´s Analytical Applications Department.
This program makes pass/fail judgments about samples in accordance with the tests specified under "Infrared Spectrophotometry" in the Japanese Pharmacopoeia. In addition to identification tests for pharmaceutical products, use this program for incoming inspections and pre-shipment inspections.
Smart Design
In addition to all the new features and functions, such as the highest S/N ratio in its class, a resolution of 0.5 cm-1, dynamic alignment, and an interferometer equipped with a desiccator, the IRAffinity-1 also achieves a reduction of approximately 20% in installation area and width (compared with other Shimadzu products).
