In this contribution we specifically address the question: How can particle size characteristics measured using different DLS instruments be compared to each other?

DLS is an effective technique for rapid measurement of size and size dispersity of nanoparticles in suspensions. To overcome limitations of current standard instruments to measure highly turbid and flowing suspensions, e.g. for process monitoring,  the NFS system with Spatially Resolved DLS  has been developed, based on 180o backscattered Low Coherence Near InfraRed light, different from standard instruments.

Spatially Resolved DLS

  • Reduction in analysis time, results in seconds
  • Increased process understanding
  • Particle size information in real time
  • Reduction of production time
  • Potential for significant batch reductions

Up to millions is lost per year due to the absence of appropriate
