Sampling
Sample Requirements for Analysis Using the Electron Microprobe
We are able to examine samples mounted in 25mm diameter blocks or as 25 x 48mm thin sections. At present we are unable to examine organic samples.
-
Samples must be vacuum compatible.
-
Polished samples are required for quantitative analysis and X-ray mapping.
-
Insulating samples need to be coated with a film of carbon prior to analysing with the electron microprobe. This may obscure features of the samples and therefore any photographs or other recording of the samples should take place prior to submitting the samples.
Sample Preparation Services
The facility can also provide access to the following services:
-
Polished Blocks: MRF offers a sample preparation facility for 25mm and 30mm cold cast resin blocks. This service includes sample impregnation (if necessary) and mounting in clear cold cast epoxy resin, grinding and polishing of samples (down to 0.02μm final polishing solution). The charges for these services depend on the type of sample and the preparation required.
