Urea analysis |
| abstract |
UREA ANALYSIS ABSTRACT OF THE DISCLOSURE Disclosed is a method and apparatus for the determination of urea in an aqueous specimen such as blood or urine. The specimen is passed through a bed of immobilized urease to hydrolyze the urea to ammonium ion. The ammonium ion is then converted to ammonia by reaction with a base. The resulting ammonia is then selectively passed as a gas through a hydrophobic, ammonia permeable membrane for potentiometric detect-ion with a pH sensitive electrode. |
