Size distributions are a description of the fact that not every component in the sample has the same size. There is a range of sizes present, as mathematically described by a distribution.
There are different ways to represent this distribution in terms of:
Intensity – How much light comes from the different components?
Volume or mass – How much volume is present in the different components?
Number – How many particles are present in the different components?
This often causes confusion, and the intensity volume number issue is one of the most popular blogs.
Intuitively most …
