Electron capture detector (ECD)

WARNING In the extremely unlikely event that both the oven and the ECD heated zone should go into thermal runaway (maximum, uncontrolled heating in excess of 400 C) at the same time, and that the ECD remains exposed to this condition for more than 12 hours, the following must be done:

After turning off main power and allowing the instrument to cool, cap ECD inlet and exhaust vent openings. Wear disposable plastic gloves and observe normal safety precautions.

Return the cell for exchange, following directions included with the form General License Certification (HP Pub. No. 43•5954•7621).

It is unlikely, even in this very unusual situation, that radioactive material will escape the cell. Permanent damage to the 63Ni plating within the cell is possible, however, so the cell must be returned for exchange.
