在线监测颗粒粉碎过程–EMS和IIPF

我最近有幸与一组非常有才华的在EMS和国际医药研究院(IIPF)工作的科学家们合作。EMS和IIPF是位于巴西Sao Paulo 西南面约一百英里的Hortolândia城市的两家制药公司。我们做了一个很有意思的项目,在原料药(API)的湿磨过程中用FBRM跟踪颗粒径的减小。传统上人们用离线激光衍射来跟踪这一工艺过程,但是这种方法被证明既费时又不准确还有潜在人身危害。

颗粒粉碎过程通过用FBRM原位跟踪颗粒的裂碎与磨碎过程,该研究组可以实时识别出每一釜湿磨的目标终点。他们还与离线激光衍射分析数据进行了关联,并得出结论“在线FBRM的使用不仅确保了一致的产品指标还使工艺过程时间降到最短”。而且,通过揭示其材料的裂碎动力学,他们得到了对工艺过程的重要理解。这种信息可以用来确保工艺放大和技术转手的成功。

与Andre Rosa, Fabiana Ribeiro 和Jose Martins (IIPF) 以及Renato Carneiro 和Ettamyr Catteli (EMS)一起进行这一项目非常愉快。他们起草了一个应用短文:在线监测用高剪切力混合器进行颗粒粉碎的过程。要得到FBRM与离线颗粒测量技术(如激光衍射、过筛)之间的关联方面的详细信息,请查看我同事Eric Dycus的 FBRM®与工艺效率和产品质量直接关联的网络研讨会

Online Monitoring Particle Milling – EMS and IIPF

I recently had the pleasure of collaborating with a group of very talented scientists at EMS and International Institute of Pharmaceutical Research (IIPF).  EMS and IIPF are two pharmaceutical companies based in Hortolândia, a city roughly 100 miles northwest of Sao Paulo, Brazil. We worked on an interesting project where FBRM was used to track Active Pharmaceutical Ingredient (API) particle size reduction during wet milling. Traditionally, offline laser diffraction had been used to track this process; however this approach proved to be time consuming, prone to inaccuracy and potentially hazardous. Continue reading
