This part of ISO 13322 is applicable to the analysis of images for the purpose of determining particlesize distributions where the velocity of the particles against the axis of the optical system of the imagingdevice is zero. The particles are appropriately dispersed and fixed in the object plane of the instrument.The field of view may sample the object plane dynamically either by moving the sample support or thecamera provided this can be accomplished without any motion effects on the image. Captured imagescan be analysed subsequently.This part of ISO 13322 concentrates upon the analysis of digital images created from either light orelectron detection systems. It does not address the method of creating the image although the detectionsettings chosen together with its calibration are important to particle sizing accuracy. This part ofISO 13322 considers only image evaluation methods using complete pixel counts.Both the type of distribution, (by number or by volume) together with the width of the particle sizedistribution has a very material influence upon the number of particles to be measured to secure thedesired accuracy within the specified confidence limits. An example is shown in Annex A.Automation of the analysis is possible in order to measure sufficient particle numbers for a requireddegree of precision.This part of ISO 13322 does not address the sample preparation. However, the sub sampling, dispersionand presentation of particles to be measured are a vital part of the operational chain of actions necessaryto ensure accuracy and precision of any final result.NOTE Further details about sampling and sample preparation can be found in ISO 14887 and ISO 14488.
