  • Analytical method validation and robustness evaluation cGMP. Routine measurements according to validated methods
  • Transfer of analytical methods for PSD determination
  • Routine measurements of any type of products

Morphology and particle size determination by Automated Optical Microscop
Morphology and particle size characterization by image analysis with Automated Optical Microscopy equipment Malvern Morphologi G3S – range 0,5 µm to 3 millimetres – according to ISO 13322-1:2014 guidelines.

  • Comparative studies to determine shape or size differences between particulate samples
  • Correlation studies of physicochemical and pharmacological properties with morphological or particle size parameters
  • Validation/Evaluation of PSD measurements obtained by Laser Diffraction

Particle Size and Z-Potential determination of nanoparticles by Dynamic Light Scattering
Particle size (nano scale) characterization according to ISO 22412_2017 guidelines and Z-Potential according to ISO 13099-1: 2012 guidelines with Malvern Zetasizer Nano ZS equipment – range 0.3 to 6000 nm.
Z-Potential determination during pH variation evolution studies (Titration).

Stability determination of emulsions and suspensions (any concentration)
