Expo Process Analytics - Model Solis™ -Spider Wheel for Inline Sampling of Heterogeneous Solids
The Solis™ interface from Expo Process Analytics is an advanced inline probe system designed to address the critical challenge of representative sampling in the manufacturing of dense heterogeneous solids. It is specifically tailored for applications in sectors requiring precision sampling, such as pharmaceuticals and polymer blends. This innovative system utilizes a rotating wheel to capture a precise volume of the powder stream, allowing for robust Process Analytical Technology (PAT) analysis. Users can vary the rotation speed, which facilitates a Quality by Design (QbD) approach, making it suitable for both process development and manufacturing contexts. The flexibility in rotation speed adjustment, controlled via a simple interface, means that it can handle a variety of materials and flow rates without necessitating hardware modifications. The operation results in consistent sample flow, enhancing process robustness and enabling hands-free operation, critical for ensuring product quality and efficiency in manufacturing environments.
Heterogeneous solids are found in a variety of products from pharmaceutical pills or tablets, cereals, or polymer blends. A key challenge in manufacturing heterogeneous solids is the ability to collect a representative sample while it is being produced for quality control or process monitoring purposes. The Solis™ interface from Expo Process Analytics addresses the challenge of representative sampling for dense heterogeneous solids and enables automated PAT for unit operations such as blending, granulation, or tablet pressing.
The Solis™ is an inline probe interface. It uses a rotating wheel that captures a representative volume of powder stream for PAT analysis. If used in process development, its ability to vary the rotation speed enables a QbD approach and streamlines analytical development. If used in manufacturing, the variable rotation speed can be changed via a controller to accommodate a variety of powder or granule types, or flow rates without needing to change process hardware. The controlled and quantified sample flow rate results in a defined unit mass that is presented to a PAT probe, resulting in increased process robustness and hands-free operations.
