Anton Paar Nova: Setting the standard for pharmaceutical surface area analysis

The reliable characterisation of excipients is critical for ensuring drug quality and regulatory compliance. In a recent study on zinc and calcium stearates, Anton Paar’s Nova series demonstrated exceptional reproducibility in BET surface area measurements, confirming its position as a trusted solution for the pharmaceutical industry.

Metallic stearates such as calcium and zinc stearate are widely used excipients in tablet production, serving as lubricants, stabilisers, and anti-caking agents. Their performance in formulations is strongly influenced by surface area, which impacts flow, compaction, and dissolution. The Anton Paar Nova series provides rapid, reproducible, and regulatorily aligned surface area analysis, enabling pharmaceutical manufacturers to confidently qualify excipients for Good Manufacturing Practice (GMP) processes.

The Nova series combines vacuum volumetric gas adsorption with up to four analysis stations, allowing simultaneous measurements and efficient laboratory throughput. For pharmaceutical manufacturers, compliance is just as vital as accuracy. The Nova series is supported by the Kaomi operating software (fulfilling FDA’s 21 CFR Part 11 requirements), ensuring full electronic records, electronic signatures, and audit trails.

With global demand for metallic stearates projected to grow steadily in the future, the Nova series empowers pharma companies to maintain rigorous quality standards while accelerating their development timelines. By combining cutting-edge analytical performance with compliance-ready data handling, Anton Paar once again sets the benchmark for pharmaceutical material characterisation.
