A 25-fold dilution was used for whole blood and plasma and a 1000-fold dilution for urine. An NH3-sensitive Ir - metal oxide semiconductor sensor was developed to detect the NH3 produced by immobilized creatinine deiminase. Endogenous NH3 was removed by the action of immobilized glutamate dehydrogenase. The sensitivity for 85 &micro;L aliquots was 0.2 &micro;M-creatinine and the calibration graph was rectilinear for up to 30 &micro;M. The results correlated well with those obtained by conventional spectrophotometry. The recoveries ranged from 93 to 105% and the only significant interferences were from low-mol.-wt. amines.',

Urine (20 &micro;L) was injected into a carrier stream of water (2 mL min-1) and merged with 50 mM phosphate buffer (pH 7.0) containing 20 mM KCl and 40 mM NaCl. This stream was split into two channels; one was passed through a short length of tubing to a nonactin-based membrane electrode which detected NH4+ ions and the other flowed through the enzyme reactor followed by a longer tube as a delay loop prior to passing through the detector. The split sample zone and addition of alkali metal ions allowed simple correction for endogenous NH4+. A rectilinear response was obtained for creatinine, even up to 80 mM NH4+. Recoveries were >99% and the coefficient of variation (n = 10) were 1.48%.',

When an aqueous sample is passed through the reactor, the mercury ions are collected and bound to the enzyme. The enzyme is partially inhibited and the amount of mercury ions is determined as a decrease in the enzyme activity. The enzyme activity is determined with an ammonia electrode when a urea solution is pumped through the reactor. The selectivity is very high and the operating range is 0-15 nM Hg2+ for 5 mL samples. The mercury can be stored for several days in the reactor before the measurements are made. Organomercury compounds give essentially the same response as inorganic mercury.',

When an aqueous sample is passed through the reactor, the mercury ions are collected and bound to the enzyme. The enzyme is partially inhibited and the amount of mercury ions is determined as a decrease in the enzyme activity. The enzyme activity is determined with an ammonia electrode when a urea solution is pumped through the reactor. The selectivity is very high and the operating range is 0-15 nM Hg2+ for 5 mL samples. The mercury can be stored for several days in the reactor before the measurements are made. Organomercury compounds give essentially the same response as inorganic mercury.',

A 25-fold dilution was used for whole blood and plasma and a 1000-fold dilution for urine. An NH3-sensitive Ir - metal oxide semiconductor sensor was developed to detect the NH3 produced by immobilized creatinine deiminase. Endogenous NH3 was removed by the action of immobilized glutamate dehydrogenase. The sensitivity for 85 &micro;L aliquots was 0.2 &micro;M-creatinine and the calibration graph was rectilinear for up to 30 &micro;M. The results correlated well with those obtained by conventional spectrophotometry. The recoveries ranged from 93 to 105% and the only significant interferences were from low-mol.-wt. amines.',
