Sample Preparation
Sample Preparation
Most samples that come into our lab are unique and as such, receive special treatment depending on what it is and how it will be analyzed.
Samples may come into the lab in any variety of size and shape. Often a metal sample need to be sectioned down to a size suitable for testing. Some samples need to be mounted in epoxy and finished with ultra fine polishing, known as "mounts".
Not all samples need to be treated. If the sample is clean and small enough to fit in the chamber of the SEM-EDS or the Spark Spectrometer, they are tested as-is. Often a sample will need to be sectioned to fit into the instrument. In order to section your metal sample to the appropriate size for analysis, we may use a precision Metallurgical Cut-off saw or one of the bandsaws.
If you are unsure how much of your sample to send, or any other questions as to how to prepare your sample before submitting it to the lab, please contact Omar directly.
