增强对结晶工艺过程的理解

科学家与工程师们经常要面对的一个挑战是如何做到增强对结晶工艺过程的理解。

EasyMax为使这些科学家与工程师们完成大量的所需工作提供了一个即功能强大又使用便捷的实验平台。看到EasyMax已被他们欢迎采纳,尤其是针对结晶工作,使人感到欣慰。Simon Rea开发了一个方法,使EasyMax更适于颗粒特征分析:

结晶终于,您可以在您的EasyMax 里同时使用FBRM和PVM了! 这一新的PTFE封盖使您有可能观察到:

  • 多晶型/晶习的改变
  • 晶种添加行为
  • 相分离
  • 工艺过程中通常的颗粒/液滴的变化

并且,这可在体积小到30毫升条件下实现!当您要放大至1升时,您还可以把同一个PVM拿到那个规模的实验中使用

要通过例子看您可以在EasyMax 里同时使用FBRM和PVM来做什么,请浏览由固态制药团队(SSPC)的Mark Barrett所作的 从实验室到生产厂反溶剂添加结晶过程的优化与放大网络研讨会系列

Enhance Your Understanding of a Crystallization Process

A common challenge faced by both chemists and engineers is how to achieve an enhanced understanding of the crystallization process.

The EasyMax has provided a powerful, yet nimble platform for chemists and engineers to get a lot of work done.  It has been great to see how well the EasyMax has been embraced, especially for crystallization work.  Simon Rea developed a way to make it even better for particle characterization:

At last, you can use the FBRM and PVM simultaneously in your EasyMax!  This new PTFE lid makes it possible to see your: Continue reading

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

Optimization and Scale-up of Fluid Bed Processes

Fluid Bed Granulation and Coating from GEA and Niro Pharma SystemsSpray layering is increasingly being used to produce spherical pellets of a target particle distribution – often with engineered dissolution profiles for time-release formulations.

This extended abstract summarizes collaborative research between GEA (Niro) Pharma Systems and METTLER TOLEDO in the application of process analytical technologies (PAT) to the monitoring, optimization and control of Precision Fluid Bed Granulation and Fluid Bed Coating.

Mining Flocculation in Minas Gerais, Brazil

I’m currently traveling in Brazil, specifically around an area called Minas Gerais (General Mines). As the name suggests, mining is the main industry in Minas Gerais; they extract almost every ore you can imagine to make metals from aluminum to zinc. Continue reading

How Process Analytical Technology (PAT) Can Optimize And Control Flocculation

Process Analytical Technology in Flocculation

How PAT Can Control and Optimize Flocculation

On July 21 and July 22, Eric Dycus will present a free online seminar – Rapid Optimization and Control of Solids Flocculation with Inline Particle Measurement Technology. This presentation will review how the implementation of Process Analytical Technology can optimize and control the flocculation process.  Eric will include examples from both laboratory and manufacturing applications to enhance and control:

  • Biotechnology cell and cell debris separations
  • Pulp and paper yield, retention, and product quality
  • Oil/sand tailings settling rates
  • Waste water settling rates in the mining industry
  • Flocculent and chemical surfactant effectiveness

World Congress on Particle Technology 6: FBRM and PVM real-time particle system characterization at WCPT6 in Nuremburg, Germany (26-29 April, 2010)

POWTECH-WCPT6-Nuremburg-METTLER-TOLEDO-FBRM-C35The particle size distribution is a critical parameter in process efficiency and product quality in many pharmaceutical, chemical and industrial processes. The real-time measurement of particle count, dimension and shape of particles as they actually exist in process provides critical process information that speeds up process understanding and enables a better means of real-time measurement and control.

At next week’s World Congress on Particle Technology in Nuremburg, two of my colleagues will be presenting papers covering research and case studies covering a variety of applications of real-time measurement of particle systems using on-line particle characterization tools.

The titles of the four papers that will be presented are listed below :

Optimization and Scale-up of High Shear Wet Granulation Processes

GlaxoSmithKline-GSK-granulation-measurement-FBRM-C35

FBRM® C35 with mechanical wiper for in situ granulation measurement

One goal of high shear granulation is to yield repeatable endpoint granule size, shape, and density distributions. This is necessary for consistent downstream flow properties, tablet consistency, and content uniformity. Quality by Design (QbD) is a concept applied to gain true process understanding through tools such as Design of Experiment (DoE), risk management, and Process Analytical Technology (PAT).

This extended abstract summarizes collaborative research between GlaxoSmithKline (GSK) and METTLER TOLEDO in the application of process analytical technologies (PAT) to the monitoring, optimization and control of High Shear Wet Granulation.
