Unit Operation: Supporting Technology

Key to any successful PAT implementation are the supporting technologies. Well designed supporting devices can make the PAT implementation much more robust. Here are just some of the examples of Expo Technologies' supporting technology.

Window Design

Expo Technologies' flush mounted window design is constructed of certified inert materials, sapphire, stainless steel 316L and Kalrez®. All window design and implementation work is performed at one of our manufacturing facilities in the US or Europe. The device is robustness tested and all documentation, including certifcates of material conformity and technical drawings is shipped with the client's modified lid. We have experience of a wide range of sizes and designs of blender lids.

Trigger Switch

Expo Technologies' trigger switch is designed to work with all ePAT blend monitoring devices and with NovaPAC© software. Manufactured from certified materials and designed to operate in classified environments, the ePAT trigger switch has undergone several hundred hours of robustness testing at various rotation speeds. The device may be modified to operate with a client's existing blend monitoring system.

Auto-Cal Unit (NIR)

Designed for Near IR based PAT devices, the Auto-Cal Unit is designed for those plant implementations where regular Performance Qualification (PQ) is difficult due to the location of the installation because either it is contained in a sealed manufacturing suite where a drug product being made is highly potent, or that simply the PAT is difficult to access on a routine basis.

The Auto-Cal Unit contains certified and traceable reflectance standards. The unit will automatically couple, run PQ and then decouple from the measurement device. It is contained in SS316L and is designed to work in classified environments.
