Energy-dispersive x-ray Γuorescence in combination with partial least-squares regression (PLSR) was used to determine nickel, copper and arsenic in aqueous solutions. Di β erent spectrum pre-processing methods (square root and logarithmic transformation and top hat Γltering) were used prior to the PL
The UV-absorption spectra of cyclo-1,3,5-trimethylene-2,4,6-trinitramine (RDX) and cyclo-1,3,5,7-tetramethylene-2,4,6,8-tetranitramine (HMX) are strongly overlapping and do not allow their direct determination without previous separation by conventional methods. A partial least squares method (PLS)
A bench-top energy-dispersive x-ray fluorescence instrument equipped with a low-power x-ray tube and a gas-filled proportional counter was used to determine CaO, SiO 2 , SO 3 , Al 2 O 3 and Fe 2 O 3 in cement. Spectrum evaluation and quantitative analysis were performed using partial least-squares (
