SRS : Spatiallly Resolved Spectroscopy
Standard Visible and Near-Infrared (NIR) Spectroscopy performs one single spectrum measurement per sample. Spatially Resolved Spectroscopy (SRS) performs measurements at different distances from the illumination point. This approach provides chemical information but also physical one such as particle size and shape, cell density, uniformity and even weight. The surface analyzed is also much more important which copes for recommendation of pharmacopeia. Several research centers have demonstrated the superiority of SRS and multipoint imaging techniques over standard NIR one.
Hy-Ternity ® and SAM-Spec ® Probes
INDATECH is currently the only company providing a full SRS/ multipoint solution for industrial applications. The best performance is achieved thanks to two important criteria :
– Unique probe design : improved during years and experience, it is protected by several patents (homogeneity measurement, weight , filling).
– Fast, robust , reliable multichannel sensor. Rather than using a standard spectrometer, Hy-Ternity® relies on push broom imaging sensor, the same as NIR hyperspectral cameras.
The software can communicate with a controller but also with standard software packages for spectral analysis such as Camo Process pulse ®, The Unscrambler®, Eigenvector PLS_Toolbox® or model exporter. Full certification CFR21 part 11 can be achieved.
