BlendView - Quality by Design

PAT, NIR & BlendView

Process Analytical Technology (PAT) is an initiative by the United States FDA to improve process control within the pharmaceutical industry. Blending has been identified as one of the prime areas of concern.

BlendView is a result of combining the world’s most advanced range of Near Infra Red (NIR) monitoring systems with the world’s largest range of tumble powder blenders. It gives real-time readouts and lets the operator determine exactly when blending is complete.

The BlendView system can work with all batch sizes from about 0.25L right up to large scale production batches.

The BlendView™ monitoring system is non-invasive and the results are obtained in real-time.

Contact Pharmatech to discuss how you can implement PAT into your tumble powder blending systems.

How do I monitor what is taking place?

The information from the NIR sampling head is analysed and is then displayed on a computer screen. The blending data can be displayed in a number of formats including easy to read graphs. All software associated with the NIR system is 21 CFR Part 11 compliant.

A laptop computer collects the blending data and provides an instant readout of blending performance
