Sample preparation
For best results grind the sample down to a particle size of approx. 200 µm.
Dry the sample to constant mass at 105°C (at least 1 hour).
Pre-heating the crucibles (1 h; 1000°C) could improve the precision.
Procedure
n Prepare ELTRA analyzer (e.g. exchange anhydrone, sodium hydroxide,
copper oxide when necessary); clean the combustions tube
n Run three warm up samples (e.g. steel samples (92400-3050) with a
minimum weight of 500 mg; add 1.5 g tungsten)
n Calibrate the analyzer with suitable calibration material (NIST or other)
(1) Weigh in 150 mg of sample in the ceramic crucibles (90150)
(2) Add 0.7 (±0.1) g of iron accelerator (90260) and 2.0 (±0.1) g of
tungsten (90220)
(3) Place the crucible on the pedestal and start analysis
Repeat Step (1) – (3) at least three times;
Mark the results and use the calibration function in the software.
