Fully automatic Kjeldahl nitrogen analyzer automatic sampling system

8700, 8900Fully automatic Kjeldahl nitrogen analyzer injection system

The Kjeldahl nitrogen determination method is a classic method for determining nitrogen. Currently, the Kjeldahl method is widely used to determine nitrogen-containing compounds in soil, food, animal husbandry, agricultural products, feed, and other fields. Using this method to determine samples requires three processes: sample digestion, distillation, separation, titration, and analysis

Our company is《GB/T 33862-2017 whole(half)Automatic Kjeldahl nitrogen analyzer "is one of the units that created the national standard, therefore it is developed and producedThe Kjeldahl nitrogen analyzer series products comply with GB standardsStandards and related international standards

8700, 8900Fully automatic Kjeldahl nitrogen analyzer automatic sampling systemSample placement capacity of 20 and 40 positions, high degree of automation (no need to manually transfer test tubes))The product with supporting equipment * has achieved unmanned and automatic analysis throughout the entire process

1. Product Features：

1) Fully automatic Kjeldahl nitrogen analyzer automatic sampling systemcanOptional models:JK9870TheJK9870ATheJK9870B

2) 8700 automatic sampler can accommodate 20 digestive tubes, 8900The automatic sampling system can be placed2a20Position the digestion tube bracket to meet the needs of batch automatic analysis

3) Sample storage adoptsRectangular structure design, after the sample is cooked, it can be directly operated on the machine together with the cooking tube rack, which is convenient and fast. Compared with disc type sample storage, it reduces the tedious operation of secondary transfer of digestion tubes

4) Automatic injection includes "continuous injection" and "individual injection"2Select and use various modes

5) The reagent tank with liquid level sensor is built into the injection system to make the workplace cleaner

6) One click start to complete 1-40 samples (or 1-20 positions): automatic injection, automatic sample replacement (more functions can be achieved depending on the selected host)

7) The injection system door is not open, and the motion system does not work switch to prevent the digestion tube bracket from moving out and hitting the door

8) Dual working position detection of the digestion tube to prevent instrument damage caused by tube jamming
