A dual spectrophotometric/contactless conductivity detector for CE determination of incompletely separated amino acids

Abstrakt

A new application is described of a dual photometric/contactless conductivity detector to CE determination of incompletely separated compounds. These compounds are differentiated when one of them provides signals in both the cells of the detector, whereas the other yields a signal in only one cell.

The technique has been applied to determination of proline and tyrosine in a dietary supplement
