NuMega operates a Perkin Elmer PE2400-Series II, CHNS/O analyzer for elemental analysis. The CHNS content is determined using the Pregl-Dumas method where your sample is prepared, introduced into the combustion chamber and burned at high temperature 925°F under pure oxygen. The resulting gas mixture and helium carrier gas pass through various reductive and catalytic zones to convert the gas mixture into CO2, H2O, N2, and SO2. The gasses are separated using gas chromatography and quantified with a thermal conductivity detector. Elemental analysis has been used for many decades in characterizing sample composition and purity. The machine can handle a wide variety of samples from solids, liquids, viscous samples, soils, and pharmaceutical agents.
Above is a diagram displaying the inner workings of our elemental analysis instrument and how the data is obtained.
