EPlater - Electro-Plater Apparatus for Alpha Spectroscopy

Electro-Plater Apparatus for Alpha Spectroscopy

Significantly improves energy resolution relative to precipitation techniques

Eliminates the chance of HF-acidic samples shortening detector life

Reduces detector contamination from loose surface material

Increases the durability of the sample for archiving or recounts

Time efficient, multiple station sample preparation

Benefits of Electrodeposition

Model EP-12 shown with optional hood

The electrodeposition of actinide samples for alpha spectroscopy provides a thin sample layer which 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 a method for acid carry over which, over time, can damage expensive detectors.

Economical cells are constructed from 20 mL polyethylene, liquid scintillation vials with the bottom removed. The standard cap is replaced with a commercially available cap which has a hole in the top for contact to the electrode. A 3/4 inch polished, stainless steel planchet is inserted into the cap with the polished side toward the solution. A platinum wire forms the other electrode; it 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. 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.

Electrodeposition systems are available with 4, 6, 8 or 12 stations depending on the number of samples that you are processing. There is also a stainless hood that will accommodate either one or two of the 12 station systems.

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.

Platinum electrode wire is NOT included. Figure either ~5inches per station with the optional electrode arm or ~10inches per station with the full electrode wire. See photos to the right. The electrode arm not only cuts the length but is more tolerant to a thinner wire gage.
