Ion mobility spectrometry is an important rapid anal. method. However, it is difficult to achieve quant. anal. when spectral peaks overlap. A new method for analyzing ion mobility spectra is presented here. The method achieves quant. anal. by combining the advantages of the peak model (in terms of optimal phys. and chem. interpretation of the system of interest) and the multiscale orthogonal matching pursuit algorithm (in terms of extracting characteristic peaks). A simulated data set, constructed using the peak model, containing overlapping peaks was analyzed to demonstrate the ability of the multiscale orthogonal matching pursuit algorithm to decompose overlapping peaks. Real data sets for Me salicylate and a mixture of acetone and Me salicylate at 16 concentrations were generated using a vapor generator (using permeation tubes). The characteristic peaks were extracted using the multiscale orthogonal matching pursuit algorithm. Univariate calibrations using the peak area and peak height were prepared to allow quant. analyses to be performed. Multivariate calibrations using partial-least-squares and poly-partial-least-squares were prepared and the results were compared with the univariate calibration results. Markedly better or similar predictions were made using the univariate calibration models involving phys. and chem. interpretations than using the multivariate calibration models.Methyl Salicylate(cas: 119-36-8Quality Control of Methyl Salicylate) was used in this study.
Methyl Salicylate(cas: 119-36-8) is a natural herbivore-induced plant volatile. It is a naturally occurring product in trees, legumes, exotic plants, vegetables, berries, and the primary constituent of the oil of wintergreen.Methyl Salicylate is produced from salicylic acid.Quality Control of Methyl Salicylate
