Abstract
The N,O-dipivalyl methyl esters of triiodothyronine and thyroxine were prepared and gas chromatographed. "Dexsil 300 GC," a heat-stable polycarboranesiloxane, was used as the stationary phase. Separations were good and prompt. As little as 250 pg of triiodothyronine was detectable. Dexsil 300 GC was used satisfactorily in measuring serum triiodothyronineKeywords
