| Abstract: | The principle of determining particle size and concentration by the use of probability theory is described. The experimental results for the latex spheres as SRM show that the presented method is reliable and repeatable. In addition, the apparatus needed is simple in constructure and easy in use.It is an effective measure for on-line industrial monitoring. |
