Alva Kd680 Kjeldahl Nitrogen Analyzer: a Professional Lab Instrument Merging Classic Principle with Advanced Automation

Product Description

Product Overview

 Alva Kjeldahl Nitrogen Analyzer is a professional laboratory analysis instrument designed and developed based on the classic Kjeldahl method principle. It combines advanced automation technology, precise sensing elements, and a user-friendly operation interface.
It is widely used in many fields such as food, feed, environment, agriculture, and pharmaceuticals. The aim is to provide accurate and efficient solutions for the determination of nitrogen content and protein content for scientific researchers and quality inspection personnel, helping various industries control product quality and promote scientific research progress.

Performance Features

*High-precision Measurement: Equipped with a high-precision ammonia sensor, it has an extremely high sensitivity to the change of ammonia concentration collected by distillation. Combined with the optimized titration algorithm, it ensures that the relative standard deviation (RSD) of the nitrogen content determination result is less than 0.5%, with minimal error in protein content conversion, meeting high-standard quality inspection requirements. For example, in the food industry, testing the protein content of milk powder can accurately identify whether the product meets national standards and protects the rights and interests of consumers.

*Automated Process: The fully automated operation covers the entire process from sample digestion and distillation to titration. Users only need to put the processed sample into the instrument and start it with one click to wait for the result. The instrument has a built-in intelligent program that can automatically adjust parameters such as distillation temperature and time according to the sample type, greatly reducing human operation errors, improving experimental repeatability, saving labor costs, and increasing experimental efficiency by 3 - 5 times compared with the traditional manual method.

*Intelligent Safety Protection: Equipped with multiple safety protection mechanisms, such as an over-temperature alarm and automatic power-off function during digestion to prevent the digestion tube from cracking due to overheating; pressure monitoring and safety valve device in the distillation system to ensure stable steam pressure and avoid danger caused by high pressure; at the same time, the instrument shell is made of insulating and fireproof materials to comprehensively protect the safety of laboratory personnel.

*Convenient Data Management: It has a large-capacity data storage function and can store no less than 5000 sets of experimental data, including sample information, experimental parameters, and determination results, making it convenient for users to trace and query at any time. The data can be exported to a computer via a USB interface for further analysis and processing, and it also supports connection to the Laboratory Information Management System (LIMS) to realize real-time data sharing and centralized management.

*Wide Sample Compatibility: Whether it is solid, liquid, or semi-solid samples, such as meat, grains, dairy products in food, soybean meal, fish meal in feed, soil, sewage in the environment, and plant tissues, fertilizers in agricultural scientific research, etc., the nitrogen content can be accurately determined on this instrument after appropriate sample pretreatment, with a very wide application range.
