Electron Microprobe Sample Holders

The Cameca SX-100 electron microprobe has a two part shuttle system that is used to hold and insert samples into the instrument. The shuttle consists of a lower rail and an upper holder.

A variety of holders can be accommodated. The one's we have at Brown are shown here. Some of the holders we purchased with the instrument, some were made by our machinist.
