On October 2, 2018, we held a seminar entitled “Overcoming Characterization Challenges in Drug Formulation” in the Boston area.  It was a great opportunity to meet with many pharmaceutical scientists in the area and learn about their challenges and concerns. …READ MORE >

What causes the most headaches for a particle characterization scientist? There are many answers to this question, but one of the most obvious is dust or contaminants! As someone who regularly uses Dynamic Light Scattering (DLS) to measure particle size,…READ MORE >

How good can a gold standard be?   When performing dynamic light scattering (DLS) measurements, we sometimes encounter especially nice data. An interesting issue to consider is the level of data quality one can expect to achieve, under ideal circumstances,…READ MORE >

The peaks in your distribution are out of order? We recently received an email about the order of peaks in the Zetasizer software: For data evaluation, is it possible to rearrange the NNLS results by order of particle size populations?”…READ MORE >

Dynamic Light Scattering (DLS), sometimes referred to as Photon Correlation Spectroscopy or Quasi-Elastic Light Scattering, is a technique classically used for measuring the size of particles typically in the sub-micron region, dispersed in a liquid. The sensitivity of some modern…READ MORE >
