Testing of visible and invisible particles

Labor LS has many years of experience in the analysis of visible and sub-visible particles – in particular according to Ph. Eur. methods 2.9.19 and 2.9.20, as well as the corresponding chapters of the USP-NF.

Complementing these services, we also offer particle size analysis using dynamic light scattering (DLS), e.g., in accordance with Ph. Eur. 2.9.50 / USP <430>. This method enables the determination of particle sizes in the nanometer range, including particle size distribution analysis. Zeta potential measurements as an indicator of colloidal system stability are also available at Labor LS.
