✦ Synopsis
The determination of C, H and O in organic liquid matrices such as solvents and di †erent base oils by principal component regression in EDXRS is demonstrated. This method is based on a signiÐcant contribution of the light elements to the backscattering of x-rays in the sample. As excitation source a Y secondary target in a cartesian geometry is used. The prediction error of the PCR calibration with respect to unknown samples is in the region of 4.0 mg g-1 for H, 30.0 mg g-1 for C and 26.0 mg g-1 for O.
