Sizing and Counting
Accurately defining the size distribution of particles in a given sample is essential for characterization during pharmaceutical and biotechnology process development, formulation and production. Standard nanoparticle sizing methods such as dynamic light scattering (DLS) can be plagued by biases introduced by contaminants. NanoImaging Services has developed advanced Molecular Microscopy image analysis software for semi-automated particle sizing and contouring that provides precise, statistically determined, and accurate sample size distribution measurement for nanometer to sub-micron particles in heterogeneous and homogeneous sample solutions.
