Other Notes: While activated cocounut charcoal is stable to above 400 °C, the temperature actually used at depends on the application. For example, thermal desorption unit (TDU) tubes are typically desorbed at 330 °C, purge traps containing just carbons typically use a 250 °C desorption temperature, and GC column applications may work best with final oven temperatures of 225 °C.
