Procedure Prepare and clean the ELTRA analyzer (f.e. exchange Anhydron， Sodiumhydroxide) and set the furnace temperature to 1350°C Run in minimum three warm up samples (f.e. ELTRA 92511-3020) with amedium sample weight of 200 mg until the results are stable Calibrate the system with a suitable calibration material (from NIST orother)： (1) Weigh in a sample weight of 150 mg in the 90160 porcelain boots (2) Start analysis (F5 Button) (3) Load the sample into the furnace and wait until the PC calculatesresults Repeat Step (1)-(3) in minimum for three times； mark the results and usethe calibration function in the software -> Analyze the unknown samples. Please introduce the wood samples slowly into the analyzer.
