氮—蛋白质分析仪是一种采用开氏法原理测定各类食物中蛋白质含量的仪器,也可用来测定土壤中的含氮量,故在农业、林业、粮食、食品和化工等部门可以广泛应用。目前,我国的氮—蛋白质分析大多数依然采用手工操作,速度慢,工作效率低。近年来,国外已开始发展了半自动或全自动的氮—蛋白质分析仪器。为了填补国内空白,发展我国的 Nitrogen-protein analyzer is a kind of instrument that uses the Kelvin principle to determine the protein content of various foods. It can also be used to determine the nitrogen content in the soil, so it can be widely used in agriculture, forestry, food, food and chemical industries . At present, most of the nitrogen-protein analysis in our country still use manual operation, which is slow and inefficient. In recent years, foreign countries have begun to develop semi-automatic or fully automatic nitrogen-protein analysis equipment. In order to fill the gaps in our country, our country is developing
