Modern and compact analyzers designed for unattended and full determination of CHN, CHNS and Oxygen in any type of sample from solid to liquid
FLASH 2000 - For reliable and precise CHN, CHNS and Oxygen determination
The Thermo Scientific FLASH 2000 Series is a range of modern and compact analyzers designed for unattended and full determination of CHN, CHNS and Oxygen in any type of sample from solid to liquid, has been the result of almost four decades of experience and innovations.
The validity of the FLASH 2000 method is endorsed by renowned international committees (AOAC, ASTM and others). The simplicity of the method, unparalleled data reproducibility and truly quantitative results is the essence of its wide acceptance by many official organizations.
The quality of FLASH 2000 data is certified to meet the numerous international round robin tests implemented for every type of material.
Accurate, simultaneous CHNS determination
The FLASH 2000 Series has streamlined all steps required to achieve precise determination of Carbon, Hydrogen, Nitrogen, and Sulfur.
The sample is weighed in Tin capsules, placed inside the Thermo Scientific MAS 200R autosampler at a preset time, and then dropped into an oxidation / reduction reactor kept at a temperature of 900 – 1000 °C. The exact amount of Oxygen required for optimum combustion of the sample is delivered into the combustion reactor at a precise time. The reaction of Oxygen with the Tin capsule at elevated temperature generates an exothermic reaction which raises the temperature to 1800 °C for a few seconds. At this high temperature both organic and inorganic substances are converted into elemental gases which, after further reduction, are separated in a chromatographic column and finally detected by a highly sensitive thermal conductivity detector (TCD).
The FLASH 2000 is not a black box instrument: the GC separation column is an open window on the analytical system; in fact the chromatogram (peak shape, peak separation, peak retention time etc.) demonstrates the real status of the instrument in every condition. The highest degree of accuracy is ensured by the complete conversion of the total sample to the elemental gases without dilution or splitting therefore without the presence of gas chambers or adsorption & desorption traps.
Versatile, precise Oxygen determination
Reliable Oxygen determination is achieved through an Oxygen-specific pyrolysis reactor heated at a temperature slightly above 1060 °C. This allows a complete pyrolysis of the sample in an oxidant-free environment. A “Nickel coated Carbon” catalyst, specifically developed for this application, ensures unprecedented precision and accuracy with a substantial reduction of analysis costs.
The MAS 200R is typically configured with a 31-sample tray, but can accept further 3 drums. In this way, MAS 200R sample capacity reaches 124 samples and it becomes a useful tool for the lab which must analyze several samples every day.
Thermo Fisher provides two liquid autosamplers suitable for all FLASH 2000 configurations: the AI 3000 and AS 3000. The AI 3000 has an 8-sample tray while the AS 3000 boasts a 105 position tray. Both liquid autosamplers are robust, precise, easy to install and easy to use.
Change of application?
The modular design of the FLASH 2000 Series CHNS analyzer means that laboratories can easily change the configuration to any other Thermo Scientific OEA analyzer, according to your needs.
