FTIR Transmission Libraries

The Transmittance spectra were measured at the Japanese National Institute of Advanced Industrial Science Technology (AIST) under strict controls. The quality of the spectra are continuously verified by expert spectroscopists. The instruments were regularly maintained and calibrated.

High purity samples were obtained from fine chemical producers in Japan and were checked using NMR and MS. Also data input was checked through secondary verification.

A comprehensive range of application specific spectra libraries according to your needs are available.

The spectra were measured with KBr, Liquid Film or Nujol with a spectral range of 4000 cm-1 to 400 cm-1

Toronto Forensic Database L70062

5.228 IR spectra from two sources: “EPA Vapor-Phase IR Library” (3.108 spectra) and from NIST laboratories (2.120 spectra).

The original EPA-IR collection contained 3,300 spectra measured by GC-IR under EPA contract. These were measured at 4 cm-1 resolution from 450 to 4000 cm-1. NIST spectra were measured on an integrated capillary GC-MS-IR instrument at 8 cm-1 resolution, most between 550 and 4,000 cm-1. Spectra included in the NIST/EPA IR data file have been baseline corrected using a single algorithm for all spectra and all have been converted to exact 8.0 cm-1 resolution. This was done to ensure homogeneity of the data. EPA spectra are given in the range 450 – 3966 cm-1, and NIST spectra were acquired from 550 – 3846 cm-1.
