Shanghai Xinjia Electronic Nitrogen Phosphorus Calcium Detector (Digesting Furnace) NPCa-02

Product Description

1、NPCa-02 Type nitrogen and phosphorus calcium measuring instrument is KDN Based on the nitrogen fixing device, it is developed by digesting and absorbing advanced domestic and foreign technologies. It has KDN The characteristics of rapid digestion and distillation of a type nitrogen fixing instrument, which replaces the catalyst with hydrogen peroxide； After the digestive fluid is volume-controlled, the content of crude protein, phosphorus and calcium can be determined respectively.

2、This catalyst has a faster digestion rate and does not leave any interfering substances in the digestive fluid that affects the determination of protein, phosphorus and calcium. That is, phosphorus is under acid conditions and interacts with ammonium molybdate to form ammonium alum acid complex, at 420 mm The phosphorus content is proportional to the absorbance of the colorimetric color at wavelength； When measuring calcium, use the disodium salt method of ethylenediaminetetraacetic acid, i.e. EDTA Law( GB6436-86）。

3、Make protein and phosphorus. Calcium is digested in one go, which not only improves the measurement speed, but also matches the national standards. Used for the determination of grain, food, feed, etc. and other agricultural and sideline products.
