Dataset-specific description

Perkin Elmer CHNS/O Analyzer 2400 Series II:

The PE 2400 is a commercially available elemental analyzer that uses a combustion method to convert the sample elements to simple gases (CO2, H2O, and N2). The sample is first oxidized in a pure oxygen environment. Elements such as halogens and sulfur are removed by scrubbing reagents in the combustion zone. The resulting gases are homogenized and controlled to exact conditions of pressure, temperature, and volume. The homogenized gases are allowed to de-pressurize trough a column where they are separated in a stepwise, steady-state manner and measured as a function of their thermal conductivities.
