Dear Dr. Meijer,
I am very happy with the results I have got using chromium with the
Finnigan Mat H/Device. There appears to be less than a 0.2% memory effect
from the chromium, possibly zero memory as the syringe used for appears to
have most of the memory.
Can chromium be substituted for uranium in your system?
