High-Throughput + Rapid Analysis: Sundy Technology Proudly Announces the Launch of the SDDN636 Dumas Nitrogen Analyzer!
In the food, fertilizer, agricultural, and environmental industries, the determination of total nitrogen and protein content is a high-frequency testing task.
In recent years, as the number of test samples continues to increase, laboratories are not only concerned with the accuracy of test results, but are also paying increasing attention to testing efficiency, automation level, and operational cost. Particularly in batch sample testing scenarios, reducing manual operations and improving continuous testing capability have become important directions for many laboratories seeking to optimize their testing workflows.
The Dumas combustion method, with its advantages of fast analysis speed, no need for chemical digestion, and greater environmental friendliness, is gaining increasingly widespread application in the food, agricultural, and related testing sectors.
Based on the practical laboratory demand for high-throughput testing, Sundy Technology has launched the SDDN636 Dumas Nitrogen Analyzer. The instrument employs the Dumas combustion method and has been systematically optimized around continuous testing capability, automated operation, and user experience, meeting the rapid determination needs for total nitrogen/protein content in the food, fertilizer, agricultural, and environmental industries.
01 Focused on Laboratory Needs — Making Testing Workflows More Efficient
The SDDN636 is not simply a matter of adding features. Instead, it has been systematically optimized around three core aspects of daily laboratory testing: throughput, efficiency, and convenience. From continuous sample loading to detection efficiency, from sample adaptability to operational experience, every design detail is intended to help laboratories reduce waiting time, minimize repetitive operations, and improve overall testing efficiency.
1 Supports Up to 144-Position Continuous Sample Loading
For laboratories that need to continuously complete large numbers of sample tests, the number of sample positions directly impacts workflow efficiency.
The SDDN636 comes standard with a 36-position sample tray, which can be expanded to 72, 108, or 144 positions according to testing requirements, enabling continuous sample loading and reducing the number of manual sample refills — ideal for laboratories with heavy testing workloads.

2 Direct Analysis of Both Solid and Liquid Samples
The instrument supports direct injection of both solid and liquid samples.
The maximum sample mass for solids is 1.5 g, and the maximum sample volume for liquids is 1 mL. No complex pretreatment equipment is required — routine laboratory samples can be tested directly, further simplifying the experimental preparation process.

3 Fastest Analysis Time: 3–4 Minutes per Sample
For different sample types, independent combustion programs can be set and saved as testing methods for direct recall later.
A single sample can be analyzed in as fast as approximately 3–4 minutes. In batch testing scenarios, this significantly improves overall laboratory testing efficiency.
4 Automated Design for Easier Daily Operation
Designed around the daily needs of the laboratory, the SDDN636 is equipped with a range of automated features:
Automatic leak check — completed with a single click;
High-precision gas flow control system for improved testing stability;
Vertical structure with a smaller footprint;
Bottom rollers and positioning mechanism for easier mobility.
These design features ensure greater stability and peace of mind during long-term instrument use.
02 Four Major Application Scenarios — Designed for Industry Needs
From the field to the factory, from raw materials to finished products, nitrogen/protein testing runs through quality control at every stage of multiple industrial chains.
With its high throughput, high efficiency, and broad sample adaptability, the SDDN636 Dumas Nitrogen Analyzer has demonstrated outstanding application value across the following four core sectors:
03 Compliance with Multiple National and Industry Standards
The SDDN636 is applicable to testing methods specified in multiple national and industry standards, meeting the total nitrogen/protein content testing requirements of the food, fertilizer, agricultural, and related industries.
