For some, at least physically, the most important question, to them, is just what the differences are between these samples in terms of particle size. So while it is the spaces between individual particles that people actually use, since so many people do want to know "particle size", we give that information here, but only because the information is asked for, not because it has any particular meaning in terms of the use of these calibration products.

Physical Appearance:

The SPI Supplies Brand gold on carbon test specimens are produced on substrates which are approximately 2 mm thick. We appreciate the problems which this causes when one is trying to work with thinner materials, but we have found that we need to keep the thickness of the substrate constant in order to get the proper distribution of the gold particles which make up the sample. We could mount the sample on a grooved mount of your choice which would reduce the discrepancy to approximately 500 µm, if specified in your order, but for some, a mount with this modification might not fit into their specimen holder.

Nominal particle sizes:

Small-10 nm
Medium-30 nm
Large-100 nm

Now the actual particle size ranges widely from these nominal values, so that the large sample may have particles as large as 200 nm and as small as 10 nm, and the "nominal" size is really only to help visualize the differences.
