Isotope separation factors of 14C-amino acids in ion-exchange on resins with carboxylic groups

The overall isotope effect in ion exchange for 12C 14C amino acids with isoionic points > 7 was measured by an automated procedure. Isotope separation factors were then calculated by use of breakthrough curves at 25° and the height equivalent to a theoretical plate for the chromatographic column...

Description
Summary:The overall isotope effect in ion exchange for 12C 14C amino acids with isoionic points > 7 was measured by an automated procedure. Isotope separation factors were then calculated by use of breakthrough curves at 25° and the height equivalent to a theoretical plate for the chromatographic column employed. They were found to be chiefly correlated with the p K 1 of the basic groups which are concerned in exchange interactions.
