A hundred samples of four types of eye tissues and hair from a set of 10 donors from the city of Prague were analyzed using INAA. The hair samples of the set of donors were taken as the indicator of the environmental conditions. Within the framework of the set of results obtained for 30 chosen elements, the differences between various types of tissues and sex were tested. The lowest trace element deposition was found for the lens tissue. The iris differs predominantly by the higher contents, particularly of metal elements. Slightly higher contents of practically all trace elements under study were found in all eye tissues taken from male donors.

The preparative separation of an enzymatic hydrolysate by a step gradient of a lithium-sodium citrate buffer was studied. Using a two-column arrangement, 10 GBq of 14C-labelled enzymatic hydrolysate or 250 mg of inactive hydrolysate were separated within 36 h. After the chromatographic separation, the fractions of amino acids were isolated from the citrate eluents on weak cation exchangers with an ethylene glycol-poly(methyl methacrylate) matrix. The use of volatile organic acids as an eluent was possible due to the weak interactions with the cation matrix.
