To improve the processing of electronic and vibrational spectroscopy data, Mnova 15 introduces an enhanced PLS-based baseline correction tool, IarPLS (penalized-least-squares based). It now features an automatic button to compute the near-optimal asymmetry parameter.

The figure illustrates the Auto Baseline Correction using the IarPLS Algorithm (penalized-least-squares based) at the bottom, with the Show Baseline option displayed at the top.

Three Normalization Processing modes, namely Largest Peak, Integral and Vector Length are available in Mnova 15. These three features aim to simplify the baseline correction process, streamline your workflow, and provide a rapid method for normalizing data to address quantitative issues.

The figure shows the outcome of Integral type Normalization after an IarPLS-based baseline correction.

Mnova ElViS supports the most frequently used data [file] formats for these analytical techniques, including import and export of single and multi-column matrix-like spectra (i.e. ASCII XY and XYY, as .txt or .csv files).

• SPC (Galactic)
• JCAMP-DX
• OPUS (Bruker)
• Single and multi spectrum SPA and SPG (Omnic)
• Perkin Elmer blocked structured (*.sp)
• ASCII (XY and XYY)

Mnova ElViS provides both manual and automatic peak picking, offering flexibility and convenience in your spectral analysis.

It also features advanced tools for the analysis of stacked or arrayed spectra, ensuring thorough data evaluation and interpretation for all your spectral needs.

Mnova ElViS comes with a bunch of very useful processing features:

• Multiplicative Scatter Correction
• Probabilistic Quotient Normalization
• Baseline correction, both automatic (IarPLS) and/or tailored (Multipoint Baseline Correction)
• Several Smoothing techniques such as Savitzky-Golay, Nonlocal Means, Exponential, etc.
• Normalization and Standard Normal Variate (SNV)
• Derivatives
• Units conversion Absorbance to/from Transmittance
