A device for opening quartz ampoules in neutron activation analysis

For trace element determinations in biological samples by means of neutron activation analysis, the samples to be irradiated in a reactor are usually encapsulated in fusion-sealed ampoules in high-purity quartz. After the irradiation these ampoules must be opened to retrieve the samples for further processing. A device was developed for this purpose which makes it possible to open these ampoules without risk of contamination of the laboratory staff and equipment and without contaminating the samples with quartz splinters.
