Abstract: A device may include a memory storing instructions and a processor configured to execute the instructions to determine an initial mass of a sample; distill the sample up to at least a thermal destruction temperature; record, at a set of time points during the distilling, vapor temperature values, liquid temperature values, and vapor pressure values associated with the sample; and determine a residual mass of the sample. The processor may be further configured to generate a pressure curve based on the vapor pressure values; calculate a summary integral surface for the generated pressure curve; and generate a distillation curve that relates the vapor temperature values and the liquid temperature values to mass percentage of the sample that has evaporated, based on the calculated summary integral surface, the initial mass of the sample, and the residual mass of the sample.
