Electrostatic Microprobe for Determining Charge Domains on Surfaces

Author(s)
Abstract
The electrostatic microprobe is a laboratory constructed instrument with the design purpose to measure charge content on wipe and various control surfaces. The device is constructed on an optical microscope platform, with a computer automated XY stage. Surfaces can be optically imaged to form micrographs of surface features as well as charge domain mapped. An ultimate goal is to quantify charge on wipe cloths to determine the influence of electrostatic forces on wipe sampling efficiency. We found that certain wipe materials do not extensively charge while others accumulate charge by making contact with other surfaces. Charge domains are found to be not uniform.Citation
