Quantitative drop analysis

Summary

Methods are described whereby amounts of ammonia and urea nitrogen of from 1,55 to 8,27 γ have been determined in pure solution, blood, and urine.

The mean error involved in these methods approximated 1 per cent, the maximum error being about 3 per cent.

The apparatus and technique described were of a simple nature, readily adapted to ordinary laboratory conditions, and, to a considerable extent, were those already developed in connection with the general application of quantitative drop scale methods to all types of analytical technique.
