Call the Nucleus before you use an elutant.  There are 2 different types of
generators.  One uses an EDTA solution and the other is the saline solution
I believe.  If you use the wrong solution you will destroy the column and
the cesium will elute along with the Barium.

The old style, that does not use EDTA, looks like a white plastic cylinder.
The new style is more like a syringe.

Call the Nucleus, Inc., (615) 483-0008 and they should be able to tell you
which one you have.
