Maintaining Your GC
Do not use solvents to clean the uECD.
You may not open the uECD cell unless authorized to do so by your
local nuclear regulatory agency. Do not disturb the four
socket-head bolts. These hold the cell halves together. United
States customers removing or disturbing them is a violation of the
terms of the exemption and could create a safety hazard.
When handling uECDs:
• Never eat, drink, or smoke.
• Always wear safety glasses when working with or near
open uECDs.
• Wear protective clothing such as laboratory jackets, safety
glasses, and gloves, and follow good laboratory practices.
Wash hands thoroughly with a mild nonabrasive cleaner
after handling uECDs.
• Cap the inlet and outlet fittings when the uECD is not in
use.
• Connect the uECD exhaust vent to a fume hood or vent it
to the outside. See the latest revision of 10 CFR Part 20
(including Appendix B), or the applicable state regulation.
For other countries, consult with the appropriate agency
for equivalent requirements.
Agilent Technologies recommends a vent line internal
diameter of 6 mm (1/4- inch) or greater. With a line of
this diameter, the length is not critical.
