SentroProbe DR LS NIR

Redefining stability for diffuse reflectance measurements

Overview

The SentroProbe DR LS is an ATEX certified probe for measurements in diffuse reflectance. It is a perfect fit to the SentroPAT FO systems and offers several feature for reliable PAT measturements in various unit operations within solid dose pharmaceutical manufacturing processes.

Two internal light sources
Internal reference for drift correction and outstanding long term stability
Probe tip with ¾" and different lengths
GMP friendly design
ATEX zone 20/21 certified

Applications

Combined with a SentroPAT FO system the SentroProbe DR LS is a powerful option to monitor many different unit operations in pharmaceutical industry but also in many applications where solids have to be measured in diffuse refelectance.

Tablet press feed frame

Sentronic has been involved in the earliest developments of PAT for tablet press feed frame, here in applications back in 2014.

Commercial Scale in Tablet Press Feed Frame

Numerous installations on tablet presses of all major brands are existent today.

Blend uniformity in various CDC setups

Sentronic systems are empowering inline control of commercial continuous direct compression lines, here used in combination with the EXPO Process TASO sampling interface.

High Shear Wet Granulation

The improvement of consistency in this unit operatoin using the Sentronic NIR solutions has significant potential and is underutilised today. In comparison to just moisture or particle size analyzers, NIR provides a unique combination of physical and chemical information.
