| 碳氢氮硫氧分析仪 FLASH 2000 |
|
碳氢氮硫氧分析仪 FLASH 2000 采用独特的“动态闪烧 - 色谱分离分析”技术。只需要极小的进样量即可获得C、H、S、N和O五种元素的精确含量。由于采用成熟的色谱分析技术，其样品燃烧分解气体采用一根内径极细的元素分析转同填充柱分离， 完全避免了由于采用大量吸附剂而存在的残留效应，使得分析结果有很好的重现性和精度。特别适合分析任务较重、样品数量较多的实验室。

* Flash Combustion
The FLASH 2000 Series Analyzer operates according to the dynamic flash combustion (modified Dumas method) of the sample for the determination of Carbon, Hydrogen, Nitrogen and Sulfur. Samples - organic or inorganic, solid or liquid – are weighed in a tin capsule and introduced into the combustion reactor by an autosampler. When the sample enters the reactor, inserted in the special furnace heated at 900 – 1000°C, a small volume of pure Oxygen is added to the system and helps to burn the organic or inorganic material, converting the sample into elemental (simple) gases. A separation column and TCD detector allows the user to determine element concentrations without using a complex splitting system, aliquote dosing device or purge & trap adsorbers. On the same instrument, but working in a different analytical condition, the Oxygen determination can be obtained when operating in pyrolysis mode. Utilizing the Flash Dynamic Combustion method, the FLASH 2000 Series achieves accurate and precise
sample characterization within a few minutes.
* Approved by official organizations
The Dynamic Flash Combustion technique is endorsed by a large array of renowned international official organizations including AOAC (Association of Official Analytical Chemists), AOCS (American Oil Chemists Society), AACC (American Association of Cereal Chemists), ASTM (American Society for Testing and Materials) and ASBC (American Society of Brewing Chemists). The simplicity of the method, unparalleled data reproducibility and truly quantitative results are the essence of this wide acceptance.
