LECO Truspec Carbon/Nitrogen Determinator
The LECO Truspec C/N Determinator is an instrument that determines the Carbon and Nitrogen content of a variety of materials, including foods, feeds, oilseeds, fertilizers, meats, and soils. The instrument is connected to an external PC and uses a Windows-based software program to control the system operation and data management.
There are three phases during an analysis cycle: purge, combust, and analyze.
In the purge phase, the encapsulated sample is placed in the loading head, sealed, and purged of any atmospheric gases that have entered during sample loading. The ballast volume and gas lines are also purged.
During the combustion phase, the sample is dropped into a hot furnace (950°C) and flushed with oxygen for very rapid and complete combustion. The products of combustion are passed through a secondary furnace (Afterburner, 850°C) for further oxidation and particulate removal. An additional furnace filter and a two-stage thermoelectric cooler remove moisture. The combustion gases are then collected in a collection vessel known as the ballast.
In the analysis phase, oxygen is injected into the ballast and mixed with the combustion gases. The homogeneous combustion gases in the ballast are then purged through the CO2 infrared detector and the 3cc aliquot loop. Once the gases have equilibrated, carbon is measured as carbon dioxide by the CO2 detector. The gases in the aliquot loop are transferred to the helium carrier flow, swept through hot copper to remove oxygen and change NOx to N2 and then flow through the Lecosorb and Anhydrone to remove carbon dioxide and water, respectively. A thermal conductivity cell is used to determine the nitrogen content.
The final result is displayed as weight percentage or in parts per million as determined by the operator. Results can be calculated on a user-defined basis – including dry-basis and total protein.
