Abstract
Novel compounds and assay methods are provided for determining the presence of lithium in serum, plasma, urine or other sample without deproteinization. The novel compounds are water soluble derivatives of TWC-crownformazans and provide signal enhancement by increased absorbance of the dye-lithium complex over the dye anion.
