            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) Place empty crucible (90190) 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)
            Repeat steps (1) – (3) at least three times;
            Mark the results and use the calibration function in
            the software.
