Sample preparation for the study of rainwater radioactivity

In order to find a connection between various global events and radioactivity in the atmosphere, rainwater is examined. Fluctuations over the course of the year are also recorded. The collected water is mixed with nitric acid and then concentrated with a large-scale rotary evaporator for further analysis.

A Bavarian institute for radiation research * is using a Distimatic Industrial Platinum 2 package for this purpose. The rainwater is collected in 40 l canisters, mixed with the acid and processed automatically at a heating bath temperature of 80°C. The result are 1-2 liters of concentrate. The throughput is approximately 300 litres per month.

Distimatic Industrial Platinum 2 package

• Glassware set with expansion vessel prevents foaming and splashing

• The automatic module automatically takes over the dosing of the medium and transfers condensate and residue into any container

• Highly resistant materials allow working with highly concentrated acids
