文摘

New method for rapid surface relaxivity calibration in siliceous porous media. Laser-induced breakdown spectroscopy used to measure paramagnetic impurities. Multivariate analysis of LIBS data used to predict surface relaxivity calibrated from MICP. Regression coefficient analysis can help find sources of relaxivity in a sample. Can be performed more quickly than traditional surface relaxivity calibration.
