Sample Preparation

In material testing and failure analysis the workpiece to be tested is typically not directly accessible to the analysis method.

A sample has to taken and prepared. This procedure has to take into consideration the specific requirements of the subsequent analysis method. Inadequate probe preparation often leads to wrong conclusions. Therefore proper preparation procedures are a prerequisite for the correct interpretation of measurement results.
