Carnitinonitrile contained in carnitine may rapidly and precisely, not being interfered by carnitine at all, be determined as follows : A sample solution buffered previously at pH 11.6 with trisodium phosphate solution is mixed with an excess amount of Reinecke salt solution. The mixture is allowed to stand, agitating from time to time and protecting from light, in ice-cold water for 50 minutes, and filtered. The excess Reinecke salt remianed in the filtrate is determined colorimetrically.
