Identification Tests

Two methods are used for Identification tests; a method performed in accordance with tests specified in the Pharmacopoeia and other
standards, and a method using spectrum matching for judgments.
Identification Testing Program

This program makes pass/fail judgments for test samples based on verification methods as described in the Pharmacopoeia and standards
in each country such as "Infrared Spectrophotometry" in the Japanese Pharmacopoeia and Food Additive Standard.
In addition to identification tests for pharmaceutical and food products identification tests, the program can also be used for incoming
inspections and pre-shipment inspections.

4 features of the Identification test program

Calculation of the differences between the peak
Prints out the spectra for standards and samples wavenumbers for standards and samples, differences in
in order to facilitate easy comparison. intensity ratios between peaks, pass/fail judgments,
and print out of reports.

Detection and printing just the peaks that are Spectra of 57 samples on Japanese Standards of
specified for pass/fail judgment. Food Additives are stored in LabSolutions IR.

Purity Judgement

The Purity Judgement calculates the similarity (Purity) between a reference spectrum and a test spectrum, and judges Pass or Fail.
It judges similarity of spectra in a quantitative way.
