Non-invasive confirmation of the identity of tablets by near-infrared spectroscopy
M. Ulmschneider,E. Pénigault +1 more
TL;DR: In this paper, the NIR-spectra of both sides of the intact tablet s were recorded in diffuse reflectance and the second derivation of the spectra was computed and spectral matching was calibrated.

In-line process analytical technology based on qualitative near-infrared spectroscopy modeling
Lars Sukowski,M. Ulmschneider +1 more
TL;DR: In this paper, the authors attempted to replace the Karl Fischer titration of individual sealed vials of an established lyophilization process by a high-speed in-line near-infrared inspection of entire batches.

Assessing the transfer of quantitative NIR calibrations from a spectrometer to another one
M. Ulmschneider,E. Pénigault +1 more
TL;DR: In this paper, the feasibility of a calibration transfer between FOSS/NIRSystems NIR spectrometers was checked, and the set of multivariate calibrations for a non-invasive identity testing and a direct determination of the water content in ceftriaxone disodium salt sterile (Rocephin ® ) and in a preparation containing tenoxicam active substance (Tilcotil® ) filled in vials, was transferred from one spectrometer to another.
