LINEAR TRANSFORMATION APPLIED TO THE CALIBRATION OF ANALYTES IN VARIOUS MATRICES USING A TOTAL HYDROCARBON (THC) ANALYZER

ABSTRACT

Total hydrocarbon analyzers provide linear responses to methane and other hydrocarbons; however, the slope and intercept are dependent on the matrix. The matrix dependency requires that calibration be conducted for each matrix gas. The application of linear transformation (LT) enables a universal calibration performed in nitrogen matrix to be used for the analysis of analytes in various matrices.
