Details

With MVAPlus, complex Raman chemical images can be processed and characterized rapidly and easily. A totally integrated module within the LabSpec6 software suite, MVAPlus has been tested and validated on a variety of datasets from small to large and with various Signal-to-Noise ratios.

Thus the MVAPlus app:

• Combines all the most common unsupervised multivariate algorithms (PCA, MCR, HCA and K-means) for loading generation with Smart Adaptative Classical Least Squares (CLS) Fitting for image generation.
• Automatically determines the reference spectra of your spectral dataset faster than ever.
• Compares, in the blink of an eye different multivariate algorithms.
• Provides a user-workflow-based interface for Raman image generation.

MVA for large and 3D samples

MVAPlus enables multivariate analysis on huge datasets up to 4,000,000 points including 3D maps.

3D multilayer polymer (230x120x400 μm 1,490,400 points)

Data Processing has never been so easy

An algorithm comparator tool is included in MVAPlus. This tool compares loadings obtained with different algorithms, allowing the most appropriate method for the analyzed dataset to be found.

Simple user interface

The MVAPlus user interface follows the natural MVA workflow, i.e. method selection, loading calculation, and finally, image generation. It automatically adjusts the image processing according to the selected method. Loadings identification is simplified with auto-identification by KnowItAll® software. Moreover, it allows the generation of additional data such as error maps, residual spectra, scatter graphs, etc.
