SentroPAT DA

Diode-array-based NIR analyser

At the core of the SentroPAT DA is a reliable and durable InGaAs diode array spectrometer. Its high spectral resolution and wavelength accuracy, coupled with low noise, make it suitable for use in demanding applications. Its superior system-to-system comparability streamlines method transfer between different instruments. Additionally, its long-term and temperature stability are of the highest quality, supported by internal intensity and wavelength references.

It offers several key benefits, including quantitative analysis of blend constituents using chemometric models, process knowledge for blend time optimisation, elimination of conventional sampling and laboratory analysis, real-time monitoring of blend uniformity, ease-of-use and minimum maintenance, reliable measurement synchronisation to the blender rotation, easy-to-clean surfaces for use in GMP production facilities, and data integrity through embedded buffering and WiFi transmission. The system is also compatible with plant-level IT and controls via OPC-server or interfaces to SIPAT or SynTQ.
