Spectral Hard Modeling – Principles and Applications (ValidNMR Webinar)

Watch our Managing Director Dr.-Ing. Clemens Minnich presenting the principles of Spectral Hard Modeling and its application for qNMR. The webinar was originally aired at September 30, 2021 by ValidNMR.

Joining Data from Multiple Sources

This article explains how to compile data from different sources - spectrometer, lab analysis spreadsheet, time information - for the subsequent creation of analysis models. It is intended for users of PEAXACT - Software for Quantitative Spectroscopy from S-PACT.

You will end up with a nicely cleaned data set to immediately continue with modelling.

Working with Data from Multiple Subfolders

This article answers a frequently asked question about how to load data files from multiple subfolders into PEAXACT.

PEAXACT Quickstart for Spinsolve Users

Welcome to PEAXACT - Software for Quantitative Spectroscopy! Are you a Magritek customer and new to PEAXACT? Or do you want to refresh your knowledge on working with NMR data? This page supplies you with useful information on how to get started quickly.

Getting Started with Quantitative NMR

This is a tutorial for PEAXACT - Software for Quantitative Spectroscopy from S-PACT. Its objective is to get you going with three features for the analysis of NMR data: NMR-specific pretreatments, Hard Models for dealing with peak shifts, and Custom Results for calibration-free quantitative analysis.

In this tutorial you learn how to:

  1. Apply NMR-specific pretreatments
  2. Create a Hard Model using a technique called Complemental Hard Modeling
  3. Test and adjust the Hard Model flexibility to deal with shifting peaks
  4. Define NMR-specific Custom Results for a calibration-free conversion of areas to concentrations
  5. Analyze concentrations of unknown spectra

If you have PEAXACT installed on your computer you may try this tutorial right away. If you don't have PEAXACT yet, get a free trial now.
