|Definition||A laboratory elemental analyser part of the EA 1110 series of analysers. It measures total nitrogen (N), carbon (C) and sulphur (S) in organic and inorganic samples. Analysis operates with dynamic flash combustion of the sample with oxygen. After combustion the resulted gases are carried by a helium flow to a layer containing copper, they are swept through a water trap, and then through a GC column, which provides the separation of the combustion gases. Finally, they are detected by a Thermal Conductivity Detector (TCD). The instrument can determine N individually or NC or NCS simultaneously depending on the analytical configuration. Combustion is at 900-1000 deg C. Reduction is at 680-780 deg C. Helium gas flow is 140 ml/min (150 kPa). Oxygen flow is 40-60 ml/min (150 kPa) and oxygen loop is 25 cc. Cycle time is 240 secs and oxygen injection time is 60 secs.|
