摘要
Abstract
Two kinds of instruments used in the automatic Kjeldahl apparatus were selected to determine the final result by using potentiometry and color methods respectively. We introduced the working principle and main parts of the two Kjeldahl apparatus;the two instruments were used to detect the protein of soybean and soybean meal, and analyzed the result. Comprehensive analysis of the two instruments in work effi-ciency, reagent consumption and maintenance cost were carried out. The results showed that: the two kinds of instruments could be used to well determine sample crude protein content. However, seeing from work efficiency and maintenance cost, the KJELTEC 8400 automatic Kjel-dahl apparatus was better than the Vapodest 50s automatic Kjeldahl apparatus. Because the Vapodest 50s automatic Kjeldahl apparatus needed longer Distillation titration time, high human participation and higher maintenance cost in late stage, the Vapodest 50s automatic Kjeldahl ap-paratus went against the laboratory work optimization.关键词
