Sörensenn.
/ˈsəːrənsən/ Chemistry.
Used attributively and in the possessive to denote a titration method employed in the estimation of amino-acids, consisting in treating the sample with formaldehyde, which combines with the amino groups, and then titrating the carboxylic acid groups against base. Sørensen first described the method in 1907 ( Compt.-Rend. des Travaux du Lab. de Carlsberg 7 1).
