Maintaining the HydrEA system
6.8.1
Cleaning the coated graphite tube
The iridium or gold-coated graphite tube in the HydrEA system can be cleaned by baking
out. This procedure can also be repeated multiple times.
The iridium coat evaporates at temperatures above 2200 °C, the gold coat at more than
1000 °C. Do not exceed these temperatures when cleaning.
