           Lab Automatic Kjeldahl Nitrogen Analyzer 

1. Manual and automatic two modes can be arbitrarily switched, and the amount of boric acid absorption liquid, alkali amount and distillation time can be arbitrarily set;
2, can store 20 sets of experimental procedures to meet the different needs of users;
3. The automatic cleaning system automatically cleans the pipeline after each sample is distilled, so that the measurement accuracy is higher;
4. The safety protection system is perfect: the digestive tube is missing, the safety door is missing, the steam oven is over-temperature and over-pressure protection;
5, automatic hydration, the amount of recovery liquid can be adjusted at will;
6, with automatic recycling alarm function;
7. Manual and automatic modes can be switched at will to meet different needs of customers.

ATN-300 Kjeldahl Equipment Automatic Kjeldahl Nitrogen Analyzer

The OLT-300 automatic nitrogen analyzer (also known as protein analyzer) is a product designed by the company based on Kjeldahl method. It is mainly used to detect food, food, dairy products, beverages, feed, Ammonia nitrogen, protein nitrogen, etc. in soil, water, drugs, sediments and chemicals.

Sample determination
1.1 Weighing
  The milk sample needs to be mixed and sampled. Because the milk sample is easy to float up and is directly sampled from the upper layer without mixing, the measurement result will be low. The milk powder sample is evenly mixed and weighed with a weighing paper and sent to the bottom of the digestive tract with tweezers. The sample remaining on the tube wall due to improper operation is flushed into the bottom of the digestive tube with sulfuric acid when sulfuric acid is added. If it remains on the pipe wall without flushing with sulfuric acid, the measurement result will be lowered.

1.2 Digestion
In the process of adding acid, the influence of the composition of the sample on the amount of acid consumed should be considered. The amount of acid is small, the sample is incompletely digested, and the measurement result is low; the amount of acid is large, and the acid is excessively mixed with the alkali in the process of the machine, and the free amine cannot be distilled out, which seriously affects the measurement result.
During digestion, pre-digestion was first carried out at 220 ° C for 1 hour and then the temperature was raised to 420 ° C. The purpose of pre-digestion is to allow the sample to react slowly with sulfuric acid. Without pre-digestion, concentrated sulfuric acid will react violently with the sample at high temperature, causing carbonization, and the measurement result will be low. The particles caused by carbonization will also block the pipeline during the waste discharge process, resulting in the instrument not working properly.
