TAAS was very effective for decreasing the retention time of the chelates including positively charged chelates strongly retained on the reversed phase stationary support. This was probably due to the preferential adsorption of TAAS on the support by the ion exchange process and the hydrophobic interaction. The use of TAAS was a promising means for improving column selectivity in RP-HPLC without depending upon the properties of a stationary support and of a mobile phase.
