It depends on which BUT you have. The older ones can be regenerated. You unscrew the fitting on one end and the pellets inside can be poured out. Agilent sells re-fill kits, and I think Restek has them as well. If you run multiple instruments from the same helium source you might look into part # 5182-9776 from Agilent and place it at the helium regulator / manifold.Hi,
I was wondering if anyone has any idea how to regenerate an agilent "big universal trap" for helium or even if they are able to be regenerated.
Thanks
