NICODOM NIR Pharmaceuticals (696 spectra)
The
near infrared spectral library "NICODOM NIR Pharmaceuticals" contains
696 NIR spectra of active substances and excipients used in pharmaceutical
industry collected in the spectral range from 4.200 cm-1 (=2.3 microns) to
11.000 cm-1 (= 0.9 microns).
The
source of the samples were local pharmaceutical companies.
((We
also offer FTIR library “NICODOM IR Pharmaceuticals”. This is a different
library. For “NICODOM IR Pharmaceuticals” –FTIR spectra - click here.))
"NICODOM NIR Pharmaceuticals" library is available
as searchable digital library compatible with your spectroscopic software.
The
sample information includes compound name (INN or commonly used), type
(excipient, drug...), purpose (emulsifier, laxative...) characteristics (color,
crystalinity...).
The spectra were collected by ThermoNicolet FTNIR
spectrometer AntarisTM, the powders were collected in glass vials on
Integrating sphere module, transparent liquids were collected in transmittance
or with a transflectance mirror.
The
basic version of this spectral library is available as book and consists of 385
near infrared spectra.
The
FT-NIR spectroscopy (typical spectral range 11.000 - 4.000 cm-1 or
0.9 - 2.5 microns) shows several advantages compared to FT-IR. FT-NIR
spectroscopy does not need any sample preparation, it allows to collect sample spectra
even without unpacking through a glass vial or polymer packaging. The influence
of sample humidity on the spectrum quality is lower.
The
NIR spectra look different from MIR spectra, usually they have broad bands
which do not correspond directly to a functional group of the studied molecule
(overtones or combination bands). The baseline shape by lower wavenumbers
(6.000 - 4.000 cm-1) is characteristic and reproducible for each
compound (when it has similar crystalinity and particle size). The baseline
slope by higher wavenumbers (11.000 - 9.000 cm-1) is characteristic
for dark or color samples, while white samples usually do not show this
feature. From this reason baseline correction was not done by the presented
spectra.
