The electrodeposition of actinide samples for alpha spectroscopy provides
a thin sample layer that is a prerequisite for optimal energy resolution.
The use of this technique has been restricted, in part, because no
commercial, multiple-station apparatus has been available. The
electrodeposition procedure itself is not a selective technique for a
particular actinide element but is easily compatible with popular
separation techniques. Electrodeposition has significant advantages over
precipitation methods that by definition add significant mass, which may
not always be firmly attached. The mass may also provide an opportunity
for acid carry over which, over time, can damage expensive detectors.
Economical cells are constructed from commonly available plastic lab
ware. A 20mL polyethylene, liquid scintillation vials with the bottom
removed makes a 3/4inch(19mm) planchet and a 125ml square bottle with its
bottom removed makes a 1inch (25mm) planchet. The standard caps are
replaced with one that has a hole in the top for contact to the electrode.
A 3/4inch polished, stainless steel planchet is inserted into the cap with
the polished side toward the solution. A platinum wire forms the other
electrode and is anchored to a binding post at the top and has a "foot"
formed just above the planchet. Agitation is automatic due to the bubbles
from electrolysis. The user can adjust and monitor the current for each
cell on its own individual meter. For the EP series all cells are wired in
parallel so that you use only the number you need at any one time and one
cell does not effect the others. For the EPX series each cell has
its own constant current power supply.
Electrodeposition systems are available as 1 or 2 position EPX
series or as 4, 6, 8 or 12 position EP series depending on the
number of samples that you are processing.

EP Series Electro-Plater
EP series systems can be set up for either 3/4inch(19mm) planchets
in 20ml LSC vials or for 1in (25mm) planchets in a 125ml square bottle.
Optional support clips are available for both configurations and an
optional stainless electrode arm reduces the length of platinum electrode
wire required.Note: Platinum is not included; see optional electrode arms,
below. |

1 220V 50/60 Hz systems all come with a 30A power supply
with a detachable, universal power cord. Non-US customers must supply
their own power cord to fit the universal socket or modify the US standard
cord to fit their local plug. Ask for your copy of the Phoenix Scientific Sales
Electro-Plater Apparatus Accessories list for suppliers and typical
prices for Platinum, vials, planchets and other accessory items. |
EP series systems can be set up for either 3/4inch (19mm)
planchets in 20ml LSC vials or for 1in (25mm) planchets in a 125ml
square bottle. Optional support clips are available for both
configurations and an optional stainless electrode arm reduces the
length of platinum electrode wire required.
