Description: Experiments show that small changes in ambient temperature cause significant shifts in apparent positions of peaks in x-ray spectra during quantitative analyses by use of electron microprobes operating in conjunction with automated wavelength-dispersive x-ray spectrometers; and one corrects for such shifts by using computer subroutine to recalibrate x-ray peak positions. Correction technique obviates frequent manual recalibration of standard peak locations and x-ray intensities of individual chemical elements, enabling operation of unattended instruments, as in overnight collection of data, and freeing analysts to spend more time interpreting data.
