Vulcan Series
When you have activated the pre-burn feature from the user interface and selected the number
of pre- burns, point the instrument at the sample and hold it steadily. Pull the trigger and wait
until the measurement is complete and the results appear on the screen. Then release the trigger.
If the results are not good and the laser beam hasn’t penetrated the surface layer, you can
increase the pre-burn intensity from the Settings menu.
Measuring aluminum profile
If the results are still not satisfactory and the laser is not able to burn through the layer of
contamination, then the sample surface needs to be cleaned mechanically.
Sample preparation – rust, paint, coatings or similar
Some surface contaminations such as thick rust, paint and some coatings are too thick to be
cleaned with the Vulcan series’ pre burn feature. In these cases the surface must be cleaned
mechanically prior to taking a measurement.
To clean the surface, use piece of sand paper or angle grinder to clean an area from where the
analysis can be taken. It is not needed to clean more than 1x1 cm (½ x ½ inch) area for the
measurement. When using sand paper or angle grinder, wipe the object clean before taking the
measurement to ensure no contamination is left on the surface from sample or grinding tools.
