Real-Time Quantification of Low-Dose Cohesive Formulations within a Sampling Interface for Flowing Powders
09 Jun 2023 | Contributor(s):: Sierra-Vega, Nobel. O., Romañach, Rodolfo J., Mendez, Rafael
This study investigates the performance of a sampling interface for monitoring cohesive, flowing powder formulations with Hausner's Ratio and Carr's Index higher than 1.5 and 35%, respectively. The sampler device was operated in combination with near-infrared (NIR) spectroscopy to quantify...
In-line monitoring of low drug concentration of flowing powders in a new sampler device

A novel sampler device for flowing powders was tested to quantify drug concentrations as low as 0.76% w/w in pharmaceutical powder blends. The sampler device was developed based on the powder flow behavior within a tablet press feed frame, following the principles laid down in the Theory of...
