Self modeling curve resolution

WebOct 23, 1999 · Self-modeling curve resolution (SMCR) describes a set of mathematical tools for estimating pure-component spectra and composition profiles from mixture spectra. WebJul 16, 2013 · In this work, we have returned to the resolution theorems by using visualization tools for calculation and demonstration the area of feasible solutions in a simulated three component system. The effect of selectivity and local rank constraints on rotational ambiguity in the results of self modeling curve resolution methods is the focus.

WebJul 10, 2009 · Self-modeling curve resolution (SMCR) was introduced in 1971 by Lawton and Sylvestre for decomposing a bilinear two-component spectroscopic data matrix into physically interpretable profiles, i.e. concentration profiles and spectra, using the minimal constraint of nonnegativity for concentrations and absorbances. Unfortunately, the … WebJan 1, 1985 · Analytical self-modeling curve resolution (SMCR) methods resolve data sets to a range of feasible solutions using only non-negative constraints. The Lawton–Sylvestre method was the first direct method to analyze a two-component system. It was generalized as a Borgen plot for determining the feasible regions in three-component systems. the mouse was invented by https://lynnehuysamen.com
