MS Resolver™

See a detailed description of the use of MS Resolver on real data Application Sheet

MS Resolver is a software package designed to resolve multicomponent data from multidetection instrumentation into the individual contributions. Unlike Xtricator, another product from Pattern Recognition Systems, MS Resolver is tailored to work with one specific type of data, i.e., mass spectroscopic data. The inherent features of mass spectroscopic data is being utilised by MS Resolver in a way impossible for a more general and complex resolution package, like Xtricator.

The biggest difference between Xtricator and MS Resolver lies in the resolution approach. While Xtricator relies heavily on interaction with the software user, MS Resolver is a fully automated resolution package. The decrease in analysis time enables one to work with more complex data than one can do with Xtricator. We have resolved data from samples containing more than 400 components using MS Resolver.

The degree of automation also makes MS Resolver a rather simple software to use. The interface is intuitive and considerable less complex than Xtricator's.

Another difference between MS Resolver and Xtricator lies in the aim of the software. Xtricator is a general-purpose resolution program. While one of the key components in MS Resolver is the resolution part, the scope of the program package is wider than this. Using MS Resolver, one can resolve data from several samples. Spectral similarity and retention times are used by MS Resolver to match the resolved components from different samples automatically. The integrated chromatographic areas for each compound in each sample are then placed in a predictor matrix, without any user interaction. This matrix can be exported and used in calibration and regression against an external response variable. MS Resolver does not perform the regression - one needs to export the predictor matrix to a general multivariate software. We recommend the use of Sirius for this purpose.

We offer a demo version of the software and we invite you to mail us if you are interested in trying this unique software.

The hardware needed for running MS Resolver depends on the amount of data going to be analysed. Smaller data sets (matrix size less than 1200 x 500) can be analysed with 32 MB of memory) while larger data sets (matrix size 12000 x 500) need at least 64 MB of memory and preferable 128 MB).
