The measure of radio-isotopes is used in nuclear medicine to control and follow the contamination level of a patient who has manipuled radio-isotopes.

Usally when measuring a radio-isotope, the first thing to do is to trap it and make it deposit on a support.

The electro-deposition system is the most efficient principle for trapping a radio-element in liquid solution.This principle allow to deposit the radio-isotopes contained in a solution onto a metallic plate. To measure the quantity of radio-element trapped, the metallic plate is afterwards placed into a suitable machine (spectrometer or other one).

WORKING PRINCIPLE

A specific electrode is diped in the solution which contains radio-isotopes. This specific electrode, in rotary movement, represents the anode of a system whose cathode will be a small metallic plate fixed at the bottom of the cell (or bottle of electrolysis).

A direct controled and constant current is then applied to this solution and will entail, by electrolysis (chemical decomposition of elements to study in the solution), the galvanic deposit of radio-isotope(s) inside the solution.

DESCRIPTION & SYSTEM INTEREST

Because of its very innovating concept, the EDP 7000 device offers efficient and original solutions for a daily use, of this type of equipment. EDP 7000 device is the first machine to use only synthetic materials in almost all constituting parts. Indeed and if atmospheres of measure are very corrosive, this type of materials guarantees an exceptional longevity for this appliance. The principle of electrodeposition entails (by JOULE effect), an important overheating of the solution in the pot of electrolysis, which usally leads to many using problems for the operator. Our machine offers a very efficient and inexpensive solution which lowers the temperature of the solution during processing . We therefore maximinize the efficiency allowed by the principle of trapping.

EDP 7000 device can be equipped with different types of sample flasks of different dimensions (3 choices : 25 cc, 50 cc or 200 cc). This possibility (that does not exist on other available competitor device, on market) presents the advantage of using very cheaper flasks.This is essential because this type of consumable must be thrown out very often (radioactive contamination of bottles). Moreover, the screw/unscrew of these 3 types of flasks is almost instantaneous and particularly easly. EDP 7000 device is equipped with an internal container for accidental liquide solution leak.

In spite of the high consumption in current of this system (5 Amperes), the up to date electronics inside this device allows working very outside its maximum capacity, guaranteing thus long periods of work without a particular fatigue of the electronic circuits. Realized with the best materials and great care, EDP 7000 is conceived to permit a fast and easy maintenance by the user himself. Indeed, and by its design, this machine allows any user to do first maintenance himself on the equipment if a problem occurs. EDP 7000 is equipped with a reverse polarity switch allowing an electro-chemical scraping of the plate (stainless steel or gold) meant to receive the deposit. Withthis method the metallic support will be pure before receiving a radionucleid. Last but not least, with a well studied price, the EDP 7000 device is certainly the first in row if you consider the ratio QUALITY / PRICE.
