Fully automatic Kjeldahl nitrogen analyzer: technical principle and function analysis

Kjeldahl method, as a classic method for nitrogen content detection, has been widely used in food, medicine and other fields. The fully automatic Kjeldahl nitrogen analyzer integrates the cumbersome distillation and condensation operations into one device through automated process upgrades, significantly improving detection efficiency and accuracy. This article will analyze its technical principles, core advantages and application scenarios, and reveal how this instrument performs laboratory nitrogen content detection.

I. Principle and core functions of fully automatic Kjeldahl nitrogen analyzer

The fully automatic Kjeldahl nitrogen analyzer is based on the classic Kjeldahl nitrogen determination principle and calculates the protein content by measuring the nitrogen content in the sample. Compared with traditional manual operation, this instrument realizes the automation of three key steps:

Automatic liquid addition system: accurately control key steps such as adding alkali, adding boric acid, adding diluent

Intelligent distillation process: automatically complete distillation and absorption operations to ensure complete reaction

Multiple safety protection: equipped with water level monitoring, anti-dry burning protection and other safety functions

II. Core technical advantages of fully automatic Kjeldahl nitrogen analyzer

1. Intelligent operating system: using Android 10 system, equipped with 7-inch touch screen, user-friendly operation interface; built-in large-capacity storage, can save 5 million test results; support data export to Excel format, convenient for subsequent analysis

2. Efficient detection process: fully automatic Kjeldahl nitrogen analyzer The Kjeldahl nitrogen analyzer can automatically complete key steps such as liquid addition and distillation; the high-speed thermal printer can realize instant output of the test report; the WiFi networking function supports direct data upload to the management platform

3. Safe and environmentally friendly design: program-controlled condensation water switch, significant water saving effect; strong corrosion-resistant components are used to extend the service life; multiple protection systems ensure safe operation
