How to Verify the Resolution of A Laser Particle Size Analyzer?

Resolution is defined as the minimum difference between two samples that can be effectively distinguished by a laser particle size analyzer. As important as repeatability and accuracy, resolution is one of the main indexes and used to evaluate the performance of a laser particle size analyzer.

Since there is no standard sample to evaluate the resolution of laser particle size analyzer, it is difficult to quantitatively assess the resolution. Users can qualitatively evaluate the resolution by a simple method: 1:1 mix two standard samples with nominal values >5. If two peaks were obtained, the resolution would be high and the instrument qualified. Furthermore, if the baseline is also separated (the maximum end of sample A is separated from the minimum end of sample B), the resolution is very high and the instrument is excellent.
