Particle Size

Particle characterization of drug substances, drug products and excipients is an important topic in research and development (R&D), production and quality control. It is also becoming increasingly important for compliance with the requirements of the FDA and European health authorities.

Pharmacological behavior of a drug product can be influenced by a change in particle size or structure. In addition, information concerning potential contamination of injections and infusions is required as part of the safety assessment of the drug. Therefore, an intensive study of API and excipient particle size, from the drug development to manufacturing, can facilitate the development of safe, stable and efficient products.

We provide a wide range of services for particle testing to support research and development, and quality control, accelerating your products’ time-to-market.

Why choose particle analysis from SGS?

We can help you with the following:

Particle size distribution analysis of solid state drug substances, drug products and excipients using sieving techniques (air-jet sieving and machine sieving)
Particle size distribution from submicron to millimeter, wet or dry, from milligram to bulk quantities of pharmaceuticals using the Malvern laser diffraction technique
Visible and sub-visible particle contamination testing
Optical microscopy/scanning electron microscopy (size, shape and elemental analysis)
Characterization by using Thermogravimetric Analysis (TGA)
Grain size analysis
Cleanliness: e.g. proof of parts cleaning efficiency by X-ray photo electron spectroscopy (XPS)
X-ray diffraction (XRD)
