- 1. Preparation of samplesin the Steel Industry Pedro Vellosillo September 2015
- 2. One of themost important steps when carrying out any type of analysis is the Preparation of the Sample
- 3. At the momentof Preparing the Samples the objective is to obtain an homogeneous reduced sample from a bigger lot
- 4. 1.- The quantityof the sample has to be enough as to be able to carry out all the necessary analysis. The sample must be homogeneous and representative. 2.- The sample has to be collected and kept very carefully to avoid any changes or contamination. 3.- The sample will need to be milled and mixed until becoming a very homogeneus powder, of the appropriate size for analysis. Make sure to avoid any kind of contamination during the process.
