FlashSmart Elemental Analyzer: Fully Automated Double Channel Analysis
Elemental analysis is an important technique in petroleum chemistry. Using an automated analyzer,
rapid and accurate weight percentage carbon, nitrogen, hydrogen, sulfur, and oxygen (CHNS/O) data can be
obtained together with the relative heat value calculation to ascertain the quality needed for better engine
performance and to help with the identification of vehicle exhaust constituents, harmful and hazardous to the
environment. Specifications and legislative limitations on hazardous and toxic pollutants from vehicle emissions have been introduced due to increasing atmospheric pollution.
The Thermo Scientific™ FlashSmart™ Elemental Analyzer is equipped with two totally independent
furnaces, allowing the installation of two analytical circuits that are used alternatively and fully automated through the Thermo Scientific™ MultiValve Control (MVC) Module
Each analytical circuit can accept its own autosampler and be configured and automatically switch between
the independent analytical setups to increase sample throughput and maximize system up-time. In this way,
the system copes effortlessly with the wide array of laboratory requirements such as accuracy, day to day
reproducibility, and high sample throughput. The MVC Module also ensures lower helium consumption (used
as carrier gas) by switching from helium to nitrogen or argon gas, when the instrument is in Stand-By Mode.
Therefore, the cost of analysis is significantly lower.
Methods
For CHNS determination the FlashSmart Analyzer operates with the dynamic flash combustion of the sample.
Samples are weighed in tin containers and introduced into the combustion reactor (left furnace) from the
Thermo Scientific™ MAS Plus Autosampler with oxygen. After combustion, the resulted gases are conveyed by a helium flow to a layer filled with copper, then swept through a GC column that provides the separation of the combustion gases, and finally, detected by a Thermal Conductivity Detector (TCD). The total run time is less than 10 minutes.
For oxygen determination, the system operates in pyrolysis mode. Samples are weighed in silver containers and introduced into the pyrolysis reactor from the MAS Plus Autosampler. The reactor contains Nickel
Coated Carbon maintained at 1060 °C. The oxygen present in the sample, combined with the carbon, forms
carbon monoxide, which is then chromatographically separated from other products and detected by the TCD
detector.
