Gains or losses of ultratrace elements in polyethylene containers.
The extent of elimination of losses and reduction of blank values in ultratrace elemental analysis can only be ascertained by comprehensive investigations for each element separately. Different, and partially conflicting precautions are found to be needed in the determination of manganese, copper, selenium, and mercury by neutron-activation analysis when polyethylene irradiation containers are used.
