Sample preparation
Make sure that the surface of the steel is free from
contaminations; otherwise clean the sample with
acetone p.a. and let dry at atmosphere.
Procedure
n Prepare ELTRA analyzer (exchange anhydrone,
sodium hydroxide, copper oxide when necessary),
clean furnace, sample drop mechanism, electrode tip
n Run three blanks with empty crucibles
n Calibrate the analyzer with suitable calibration
material (NIST or other)
(1) Fill one empty inner crucible (90180) in one outer
crucible (90185) and place them on the electrode
tip, close furnace (F2 Button)
(2) Weigh calibration material (usually pins)
(3) Place calibration material in the sample
drop mechanism and start analysis (F5 Button)
After analysis give the inner crucible into waste and
fill in a new one. The outer crucibles can be used
approximay 10 times.
Repeat steps (1) – (3) at least three times;
Mark the results and use the calibration function in
the software.
