“…The applications of this method include the determination of ammonia in Kjeldahl digests (Mann, 1963;Dambacher et al, 1968;Gehrke et al, 1968), in boiler feed water (Tetlow and Wilson, 1964), and urea after hydrolysis with urease (Skendzel and Muelling, 1967). Lorentz (1967) also used this method for urea estimation but employed salicylate in place of phenol.…”

SUMMARY A technique for optimising reagent concentrations on the AutoAnalyzer has been applied to the estimation of ammonia by the Berthelot reaction in the determination of urea and organic nitrogen. Comparison of the use of phenol and salicylate revealed that the optimum concentration of the latter is about four times that of the former. The optimum concentration of hypochlorite is five times greater with salicylate than with phenol, and for the catalyst, sodium nitroprusside, the factor is two. The precision obtained with the different methods is similar.

“…This means, in other words, that a satisfactory value reported by the surveyed laboratory would agree with 95 per cent of the determinations made by the reference laboratory. 13 The results of this survey seemed to cast a brighter light on small hospitals than had other studies of the quality of care in these institutions. The investigators report: "Survey results indicate that laboratory performance in small hospitals is much better than some have pictured it.…”
