Continuous Monitoring and Reporting of Instrument Status

Increased Reliability Achieved by Instrument Monitoring

In order to increase reliability, not only does the IRAf nity-1S execute self-diagnosis at initialization,
it also monitors the state of the instrument during operation. It is also possible to check basic
performance using a validation program that is incorporated as a standard feature.

Sequential Display of Diagnostic Results

The IRAf nity-1S executes self-diagnosis at instrument initialization,
in which it checks the electrical, signalling, and optical systems.
If the interference conditions are poor, they are adjusted and optimized
using the dynamic alignment mechanism. Additionally, the light source,
the He-Ne laser, humidity, information related to accessories, and the
auto sample changer settings are continuously monitored by the status
monitor function. If accessories are installed, they are automatically
identi ed, and the optimum measurement conditions are set*.
These diagnostic and monitor results are recorded in logs.
*Only when QuickStart accessories are installed.

Validation Program

The IRAf nity-1S is equipped with a validation program that complies
with the European and Japanese Pharmacopoeias and with ASTM
(American Society for Testing and Materials). This validation program
checks the basic performance of the instrument using a polystyrene
lm, and creates reports of the results.

• Test Items Complying with the European, Japanese, and Chinese
Pharmacopoeias

• Shape and intensity of a power spectrum
• The following items for a polystyrene spectrum:
• Resolution
• Wavenumber accuracy
• Wavenumber reproducibility
• Transmittance (absorbance) reproducibility
Example of ASTM
• Test items for ASTM (ASTM 1421 Level Zero) report output
• Energy intensity test based on power spectrum
• Noise test based on 100% transmittance spectrum
Example of Japanese Pharmacopoeia
• Reproducibility test based on polystyrene spectrum
