In this video, we take a show TKN analysis, a critical method for determining total Kjeldahl nitrogen (TKN) in soil and wastewater samples. 

TKN is a key indicator of the nitrogen content in environmental samples, providing critical information for monitoring and assessing environmental impacts. We demonstrate each step of the Kjeldahl method for TKN determination, which involves digestion, distillation and titration, and how it can be applied to both soil and wastewater samples. 

During the video, we will also highlight the importance of accessories that you can use that are specific for environmental samples, emphasizing the need for analytical safety to protect both the operator and the sample.

We will also show how to efficiently determine nitrogen by using an autosampler and automatic dosing, aspiration and titration which is improving the efficiency and accuracy of the overall analysis process. 

Join us as we delve into the world of TKN analysis, exploring the steps to determine Kjeldahl nitrogen in soil and wastewater samples. With the Kjeldahl method and the latest features in distillation units, we can achieve reliable and accurate results, contributing to a safer and healthier environment for all purposes.

The Art of Spray Drying: Poster Overview

In this video, we demonstrate the revolutionary Zero Tube Movement Principle in Kjeldahl nitrogen determination method, showcasing a safer and more efficient workflow for the digestion, distillation, titration, and cleaning processes in TKN (Total Kjeldahl Nitrogen) determination.

The Zero Tube Movement Principle eliminates the need to handle individual sample tubes throughout the analysis, significantly improving safety and reducing the risk of accidents. By keeping the samples securely contained in a specially designed rack, we ensure a controlled environment while streamlining the workflow.

The sample tubes are initially placed in the rack, which is then transferred to the digester for the digestion process. This step ensures thorough decomposition of samples while maintaining their integrity.

Once the digestion is complete, the rack is placed into the autosampler and the samples are smoothly transferred via steam to the distillation unit. This innovative technique allows for the quick and easy transfer of samples from the rack to the distillation unit, eliminating the need to handle individual glass sample tubes. This seamless automation of this step enables saving time and reduces the risk of human error.

Furthermore, as the analysis nears completion, the sample tubes within the rack are prepared for cleaning using the retaining plate. This ensures efficient and uniform cleaning of the tubes, promoting consistency in subsequent analyses. Finally, the sample tubes are effortlessly loaded into the dish washer, simplifying the cleaning process and preparing them for future use.

Join us in embracing the Zero Tube Movement Principle, a groundbreaking approach that enhances laboratory safety, streamlines workflows, and optimizes productivity.
