Aug 28, 2013· Sputter coating for SEM is the process of applying an ultra-thin coating of electrically-conducting metal – such as gold (Au), gold/palladium (Au/Pd), platinum (Pt), silver (Ag), chromium (Cr) or iridium (Ir) onto a non-conducting or poorly conducting specimen. Sputter coating prevents charging of the specimen, which would otherwise occur because of the accumulation of static electric fields.

The main thing to remember about the use of a gold pan is that while it is very effective as a gold-catching device, it can only process a limited volume of streambed material. For this reason, the gold pan is normally not used as a production tool in commercial use, other than in the most remote locations where it would be very difficult to haul large pieces of equipment, and where there is ...
