The calibration of a particle analyser can be performed using certificated reference material (CRM) or general reference material (RM). CRM was verified by the qualified or regulatory departments and the data was released with scheduled dates. At…

In addition to certificated reference materials, many instrument manufacturers also introduced the general reference materials (or working standard materials), which are used for the verification of instrument repeatability, reproducibility and even…

Four main parameters are used to evaluate the performance of a particle size analyzer:(1) Sensitivity: refers to the change in test results when two samples with very small size difference (e.g., D50 difference of 1μm) are measured.(2) Resolution:…

Why Do Different Particle Size Analyser Produce Different Results?In particle sizing, we often encounter a situation: for the same sample, different instruments could produce different results. Some powder manufacturers and users tend to judge the…
