Discussion on performance evaluation method of particle size analyzer

This article first puts forward the viewpoint that “accuracy” should not be used as an important indicator for evaluating the performance of particle size analyzers, and demonstrates it. It is proposed to use repeatability, authenticity, ease of operation, measurement (dynamic) range and other indicators to form an evaluation index system for the performance of the particle size analyzer. In the end, the article pointed out several misunderstandings about the user's understanding of the performance of the particle size analyzer: "Foreign subject", "First-enter subject", and "Can measure the largest particle".
