凯氏定氮仪对蛋白的高效定量检测技术已在食品、饲料等行业中广泛应用，并在原料的验收和产品建业过程中发挥着不可替代的作用。目前国内尚未制定出对凯氏定氮仪的校准验收标准。本文通过研究发现，可以通过硫酸铵来验证滴定系统的准确性，L-色氨酸来验证消化系统的稳定性，从而确定出检定凯氏定氮仪简单、快速的验收方法。

The kjeldahl nitrogen determination apparatus to protein effcient quantitative detection technology has been widely used in food, feed and other industries, and in the process of acceptance of the raw materials and products and thus play an irreplaceable role. At present domestic has yet to develop the kjeldahl nitrogen determination instrument calibration acceptance criteria. In this paper, the study found that can verify the accuracy of titration system by ammonium sulfate, L - tryptophan to verify the stability of the digestive system, so as to identify veriifcation kjeldahl nitrogen determination apparatus is simple and rapid method of acceptance.
