Total Sulfur & Carbon Content

IMG_1529The sample is weighed, placed in the LECO furnace, and combusted at a high temperature in a pure oxygen environment.  The carbon oxidizes to form carbon dioxide (CO2) and the sulfur becomes sulfur dioxide (SO2). The concentrations of the SO2 and CO2 generated from the sample are measured in an infrared (IR) cell. The instrument converts these concentrations into percentages (and/or ppm) of total carbon (TC) and total sulfur (TS) present in the sample, taking into account the sample weight, calibration and known moisture value of the sample.
