I used a shareware program called WPlot, I copied the graph to the ClipBoard (copies as a bitmap) pasted into a graphics program, reduced colours to two and saved as a Gif file.

I had run out of KNO3 buffer and so the readings were drifting a bit and I couldn't afford the time to let the measurements settle. Must invest in a magnetic stirrer, as long as that doesn't upset the ions, then I will be able to measure without a buffer. Anyway the all important last measurement put the curve into perspective, and it is not drawn freehand, but by the graph program. > What will remain to be shown is the degree to which this kind of > calibration will transfer to other production methods where the > particle size distribution and/or charge characteristics, etc, are > different.
