The PolySense team has just published a new article on Analytical Chemistry journal reporting on a  statistical tool based on partial least squares regression (PLSR) able to retrieve single-component concentrations in a multiple-gas mixture characterized by spectrally overlapping absorption features exploiting QEPAS spectroscopy. The following link provide access to the article. http://polysense.poliba.it/wp-content/uploads/2020/07/121_acs.analchem.PLS_2020.pdf
