CAE Grand Ouest, a laboratory within the Veolia Group located in Western France, specializes in environmental analysis, particularly in water and soil. They evaluate pollution levels through the determination of key parameters like Ammonia and Total Kjeldahl Nitrogen (TKN).
The laboratory’s expertise extends to the meticulous analysis of multiple wastewater and soil, these parameters serve as a critical metric for assessing the environmental well-being of ecosystems.
Their standardized procedure involves samples undergoing a thorough digestion process with sulfuric acid, converting Nitrogen into Ammonium Sulfate. This is followed by a carefully orchestrated series of steps involving alkalization with Sodium Hydroxide, Automated steam distillation, and titration ensuring precise and reliable results.
BUCHI equipment; including BUCHI’s KjelMaster K-375 with KjelSampler K-377, Scrubber B-414, and Digester, (with all units available locally from Labotec) is used for their comprehensive environmental and pharmaceutical analyses. This equipment allows the laboratory to efficiently process up to 120 samples daily with full automation, minimizing user intervention during the analysis. The integration of the BUCHI Digester, KjelMaster K-375, and KjelSampler K-377 not only accurately streamlines the workflow but also results in significant time saving, enhancing overall productivity. The sample transfer of the Autosampler (K-377) facilitated by steam overpressure, adds a layer of convenience, reducing maintenance time. The Digesters are compatible with the 48-position Autosampler, allowing easy transfer from Digestion to Distillation. The potentiometric or colorimetric titration modes of the K-375 Distillation Unit provides a versatile and efficient system, ensuring accurate and precise results, improving the laboratory’s turnaround time.
The implementation of steam overpressure for sample transfer proves to be exceptionally convenient, simultaneously decreasing maintenance and hands-on time. The Digestion rack compatibility with the 48-position Autosampler K-377 and the versatility offered by the potentiometric and colorimetric titration modes of the K-375 distinguish their system, contributing to heightened efficiency and productivity in the laboratory.
