FAQ - Frequently Asked Questions

After measurements are repeated many times, the seal (PTFE ring) may be contaminated with soot or smoke generated from samples. If the contamination becomes severe, the sample itself may be contaminated. Clean the seal before measurement or when replacing the graphite tube.
Remove the seal from the graphite holder and soak the seal in distilled water or alcohol to remove dirt, and then wipe away all moisture using tissue paper or gauze. After the cleaning, with the wide surface of seal directed toward the graphite holder (right-hand cooling block), mount it to the graphite holder.
