title: Chemical test of phosphates in urinary stones by means of the chromatographic contact print method.
abstract: The chromatographic contact print method, making use of the ammonium phosphomolybdate-ascorbic acid reaction, is used to detect phosphates and to view their distribution in urinary stones. This sensitive reaction may take place even if phosphates, especially apatite, are present in such small amounts as to be under the confirmation limits of microscopic observation, and X-ray and infrared analyses.
