The only serious drawback to the Kjeldahl method of nitrogen determination is the breakage of distilling flasks, and in laboratories where many determinations of albuminoid nitrogen are made by the Stutzer process this breakage is often a matter of much annoyance and considerable expense, since only the best quality of flasks will long stand the requirements of the process.
