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
(Contaminant analysis program and a Japanese PharmaReport
program) make it easier to perform data processing and analysis.
*As of January 2008, according to Shimadzu investigations.
Highest S/N Ratio in Its
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

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 auto dryer (JPN:registration
of utility model No.3116465).
Equipped with Analysis Support
The two main applications of infrared analysis are the analysis
of contaminant 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
Contaminant Analysis program
By combining a library of spectra for substances that are
often detected as contaminant and Shimadzu's own algorithms,
this program identifies contaminant 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 contaminant in Shimadzu’s Analytical
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.
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 an auto dryer, the IRAffinity-1 also achieves a reduction of approximately 20% in installation area and width (compared with other Shimadzu products).
