Title: Innovations by Wolfgang Hirsch in Diagnostic Agents
Introduction
Wolfgang Hirsch is a notable inventor based in Luthe, Germany. He has made significant contributions to the field of diagnostic agents, particularly in the detection of ketones and urobilinogen. With a total of two patents to his name, Hirsch's work has implications for medical diagnostics and health monitoring.
Latest Patents
Hirsch's latest patents include a process for the production of a diagnostic agent for the detection of ketones. This innovative process involves an absorbent carrier that is first impregnated with an aqueous solution of an amino acid and tetrasodium ethylenediamine tetraacetate as a buffer. After drying, the carrier is impregnated with a solution of sodium nitroferricyanide in a solvent mixture that includes methanol, followed by another drying stage. This method improves upon previous techniques by using alternative solvents to dimethyl formamide, which is known to be detrimental to health.
Another significant patent by Hirsch is a test composition for detecting urobilinogen. This composition utilizes 4-fluoro-3-nitrobenzenediazonium salts, which allow for specific and sensitive determination of urobilinogen without interference from bilirubin in aqueous solutions or body fluids such as urine. The diazonium salts are enhanced with special stabilizing anions, and the test device comprises a bibulous carrier member, such as paper, that is impregnated with the test composition in dry form.
