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.
