Product Application

The Kjeldahl 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 industries. When using this method to determine samples, three processes are required: sample digestion, distillation separation, and titration analysis

DigiPREP TKN SystemsJQ9870 seriesIt is a fully automatic distillation developed based on the classic Kjeldahl nitrogen determination method——Titration technologyColor methodDetermining the endpointThe method and manufacturing of the "nitrogen element" (protein) analysis system comply withManufacturing standard and relevant international standards for GB/T 33862-2017 Fully (Semi) Automatic Kjeldahl Nitrogen Analyzer

Product Features

«No need for tap waterDigiPREP TKN SystemsEquipped with an efficient chilled water circulation system controlled by a nitrogen analyzer host, it is energy-saving, environmentally friendly, and has good stability

«The internal standard of titrant concentration eliminates systematic errors caused by differences between human and instrument judgment, with high accuracy and convenience

·sample weighingAutomatic data upload and input, reducing the tedious work and input errors of manual input one by one

·Distillation and titration are carried out simultaneously in the mode of simultaneous distillation and titration. When the titration reaches the endpoint, distillation ends simultaneously, which can save analysis time

·Automatic discharge of digestive waste liquid reduces labor intensity for workers

·Steam flow rate can be adjusted from 50% to 100% to accommodate samples of different concentrations

·The steam system provides a constant pressure steam flow rate, with good stability and safety

«Shut down and automatically clean the alkali pipeline to prevent blockage and ensure accurate liquid supply

·Cooling water flow monitoring can prevent insufficient cooling water flow from causing sample loss and affecting analysis results

«Measurable through delay analysisNitro class samples

Reliable execution system

·Selecting R, G, and B color sensors, with a wide range of color adaptability, high accuracy, and fast response speed

·Composed of a German made linear motor and injection needle tubeThe plunger titration pump has high control accuracy and good stability

·Metal material（304 stainless steel steam boiler: stable performance, reliability, and strong pressure resistance

Convenient operating system

·The embedded operating system with independent intellectual property rights adopts a 10 inch color touch screen, and the menu is a Chinese character human-machine dialogue mode, which is easy to operate and learn

«Automatic shutdown function, system60 minute unmanned operation automatic shutdown, energy-saving, safe, and reassuring

·The operation method, reagent preparation, precautions, and maintenance are placed on the screen for users to easily query and use

·R. The three titration curves G and B can observe the changes in the sample during the titration process, providing assistance for the analysis process

·Titration accuracy verification can ensure the accuracy of analytical data

·The titration cup is installed in an open manner, making it convenient for users to observe the titration process and clean the titration cup

·The instrument has a built-in protein coefficient query table for users to access, query, and participate in system calculations, making it convenient for users to use

·Automatically upload and input sample weighing data, reducing manual input of tedious work and input errors one by one

«16M data storage capacity can store 100000 sample data for users to view, 5.7CM automatic paper cutting thermal printer

·99 groups of users set up their own program (recipe) management system

·Multi functional interface can be connected to refrigeration system, reagent tank level sensor

Secure protection system

·Leakage protection system prevents leakage and electric shock, ensuring the safety of operators

·Digestive tract deficiency system does not add reagents or heat to prevent injury from reagents or steam

·The safety door is not closed and the system does not work. The 5mm thick transparent safety door ensures personal safety

·Automatic shutdown and alarm of steam system water shortage system to prevent accidents from occurring

·Automatic shutdown and alarm of steam boiler overheating system

·Steam overpressure system alarm shutdown to prevent accidents from occurring

·Sample over temperature alarm can prevent the sample temperature from rising and affecting the analysis data

·The safe alkali addition mode can reduce the strong reaction during the alkali addition process and prevent the occurrence of tube bursting
