The Element5 820 CHNSO Element analyzer is a high-quality organic element analyzer produced by PRI-ECO with the technology of NCT (formerly Costech) in Italy, combined with Dumas' dynamic flash burning technology and chromatographic separation. It can measure carbon, hydrogen, nitrogen and sulfur through oxidation process, or oxygen through reduction process. The Element5 800 series is an upgraded and expanded version of the 600 series products, adding the automation function of the equipment, that is, the automatic system leak detection, automatic flow rate setting, intelligent oxygen distribution and other functions. Like the 600 series, the Element5 800 series element analyzer can be selected in single and dual furnace design to distinguish whether oxidation and reduction processes are carried out in a single furnace or in a dual furnace; Different diameter oxidation and reduction tubes can be selected to meet the test requirements of different types (such as solid and liquid) and different carbon content samples (from micrograms to grams), and corresponding to different measurement samples, configured with different oxygen dosages to save consumables; Dynamic sampler or automatic sampler can be selected to meet the needs of different injection operations and injection quantities; The innovative design of the TCD detector has a self-calibration function, does not need to use reference gas, maximize the optimization and enhance the customer experience.
Oxidation and reduction of the Element5 820 CHNSO element analyzer is carried out in two furnaces, oxygen usage and consumable status are fully controlled, and intelligent automatic leak detection is available.Element5 820 inherits the excellent quality of NCT's products. In the optimization process of PRI-ECO, its stability and applicability are further improved, and can be widely used in ecology, agriculture, medicine, Marine research, food analysis, petrochemical, quality control and other industries and fields.
