Micromeritics Predictive Materials Science Solutions for the Identification and Control of Critical Quality Attributes

Quality by Design (QbD) is a systematic approach to development that begins with predefined objectives and emphasizes product and process understanding and process control. Achieving QbD requires an in-depth understanding of physicochemical properties.

Early identification of Critical Quality Attributes (CQA) of excipients and active pharmaceutical ingredients (API) and their impact on a formulation is a key component of QbD. Micromeritics’ instruments and contract analytical services offer solutions for the early identification of CQA’s, continuous process monitoring, and verification, which are the foundation of QbD. Historically, particle size has been the dominant physical characteristic control parameter for release. But now, properties such as surface morphology, porosity, particle shape, density, and surface energy are additionally utilized as predictive tools to reduce possible manufacturing failures by predicting scale-up effects on the final product.

Backed by Micromeritics with 50 years of experience, Micromeritics Pharmaceutical Services will be your trusted materials characterization solution for pharmaceutical materials, medical devices, nutraceutic and other FDA-regulated products. Through the use of advanced analytical testing systems, MPS provides solutions for the optimization of your drug development and production processes.






Early identification and understanding of Critical Quality Attributes (CQAs) are essential steps in the process. From a QbD perspective, scientists, researchers, and regulators look for consistency, both in physical and chemical attributes. MPS is here to help you define, specify, and control the critical quality attributes of your materials.
Our areas of expertise include particle size distribution analysis (micrometer and nano particles), particle shape and morphology, surface area, surface energy, vapor sorption, porosity, density, thermal analysis, and material flow properties.

Using a SpinTester to Accurately Predict Hang-Up Issues In Process Equipment









White Paper: How To Administer Insoluble Active Pharmaceutical Ingredients- Solid dosage forms (tablets and capsules) are the most common and effective way to administer drugs, making up about 60% of all drug delivery methods. These range from treatment of cold symptoms to head aches to allergies to gastro-intestinal discomfort, and so on. Brands like Tylenol and Advil have become household names...
