Nitrogen analyzer: a precise and efficient tool for nitrogen and protein analysis

Accurately measuring the nitrogen content in samples and calculating the protein content is a fundamental and crucial analytical task in many fields such as food quality, feed nutrition, environmental monitoring, and agricultural research. The classic Kjeldahl nitrogen determination method has become an internationally recognized standard method due to its reliable principle and accurate results. The Hengmei nitrogen analyzer is based on this classic method, and through highly integrated and automated technology, transforms tedious manual operations into efficient and accurate instrument analysis processes, becoming an indispensable core equipment in modern laboratories.

The core value and importance of nitrogen analyzer

Standardization cornerstone: Strictly following national standards (such as GB/T 33862-2017) to ensure the authority and comparability of test results is the foundation for product quality control, reliable scientific research data, and regulatory compliance.

Efficiency Revolution: It integrates the time-consuming and error prone core steps of distillation, absorption, and liquid addition in the traditional Kjeldahl nitrogen determination method into one instrument for automatic completion. This not only significantly shortens the detection time for individual samples, but also significantly reduces the labor intensity and technical dependence of experimental personnel.

Precision Guardian: Automated operations reduce sources of human error (such as inaccurate liquid volume, improper distillation time/temperature control), combined with precision controls and sensors built into the instrument, ensuring high repeatability and accuracy in each detection, providing solid data support for scientific research and production decisions.

The outstanding advantages of nitrogen analyzer

Hengmei nitrogen analyzer (such as high-end models that comply with GB/T 33862-2017 standard) integrates numerous advanced features to comprehensively improve user experience and data management efficiency:

Intelligent operation center: equipped with Android 10 system and 7-inch touch screen, the interface is intuitive and friendly, parameter settings, program operation, and status monitoring are clear at a glance, and the operation is easy to get started.

Full process automation: Automatically complete alkali addition, boric acid absorption solution addition, dilution solution addition, distilled water addition, and key distillation and absorption processes, freeing hands and improving efficiency and consistency.

Multiple safety nets:

Real time monitoring of evaporator water level and protection against dry burning to ensure safe operation of equipment

Monitoring the flow rate of condensate and detecting the temperature of the condenser tube to ensure condensation efficiency and prevent sample loss or result deviation.

Multiple monitoring of evaporator water level, temperature, and pressure to establish a comprehensive safety guarantee system.

Key components are made of strong corrosion-resistant materials to extend their service life and adapt to complex sample environments

Powerful data management capabilities:

Massive storage (16GB capacity), easily storing over 5 million test results, and historical data can be accessed at any time.

The results are directly generated in Excel spreadsheet format, which facilitates subsequent statistical analysis and can be copied and exported directly through a USB drive.

Support batch printing of detection reports (equipped with high-speed thermal printers that can automatically print), as well as batch uploading of data.

Built in WiFi networking function, the test results can be seamlessly uploaded directly to the designated platform or LIMS system, achieving real-time data sharing and traceability.

Intelligent environmental design: The program intelligently controls the opening and closing of condensate water, only supplying water when needed, significantly saving water resources, in line with the concept of green laboratory.
