Second-Order Data Obtained by Time-Resolved Room Temperature Phosphorescence. A New Approach for PARAFAC Multicomponent Analysis
A second-order multivariate calibration approach, based on a combination of PARAFAC with time-resolved room temperature phosphorescence (RTP), has been applied to resolve a binary mixture of Phenanthrene and 1,10-Phenanthroline, as model compounds. The RTP signals were obtained in aqueous β-cyclodex...

description | A second-order multivariate calibration approach, based on a combination of PARAFAC with time-resolved room temperature phosphorescence (RTP), has been applied to resolve a binary mixture of Phenanthrene and 1,10-Phenanthroline, as model compounds. The RTP signals were obtained in aqueous β-cyclodextrin solutions, in the presence of several heavy atom containing compounds. No deoxygenation was necessary to obtain the phosphorescence signals, which adds simplicity to the method. The resolution of the model compounds was possible in base to the differences in the delay-time of the RTP signals of the investigated analytes, opening a new approach for second-order data generation and subsequent second order multivariate calibration. |
