The Element5 624 CHNSO elemental analyzer is a high-quality organic element analyzer produced by YUKE using technology introduced from NCT (formerly Costech) of Italy, combined with Dumas "flash combustion" technology and chromatographic separation. It can measure carbon, hydrogen, nitrogen, and sulfur elements through an oxidation process, or measure oxygen elements through a reduction process. The Element5 600 and 800 series elemental analyzers offer single-furnace and dual-furnace designs, allowing for the determination of whether the oxidation and reduction processes are performed in a single furnace or in a separate furnace. Different diameters of oxidation and reduction tubes are available to meet the testing needs of different sample types (such as solids and liquids) and carbon contents (ranging from micrograms to grams). Different oxygen dosages can be configured for different sample types to conserve consumables. Manual or automatic sample injectors are available to accommodate different injection operations and sample quantities. The innovative TCD detector features a self-calibration function, eliminating the need for reference gas and maximizing the user experience. Furthermore, the Element5 800 series analyzers are equipped with intelligent automated leak detection and automated flow rate control.

The Element5 624 CHNSO elemental analyzer is an economical single-furnace design, performing oxidation and reduction in a single furnace. Element5 624 inherits the excellent quality of NCT products, and through the optimization process of Preeco, the product stability and applicability have been further improved. It can be widely used in many industries and fields such as ecology, agriculture, medicine, marine research, food analysis, petrochemicals, quality control, etc.
