Vikki; Don't sweat -it. Just note the Ic0 (inital cell current) and plan from there, Keep a good data log noting Ic0, Icf, Rb, time, color, and if you get a ppm add it. Icf is final cell current.
For a fixed set-up you will soon have the problem by the tail. Keep switching, and add stirring it shortens the time and mkes smaller particles. You will note this in the laser beanwidth and density. No one has talked about beam width, but I ahve many smples in clear bottles and the beam width ans density are remarkable as indicators of particle size.
