MQ - MALDI

Offers qualitative and quantitative analysis of MALDI MS spectral data in high-throughput manner. User-friendly interface with an array of configurable features for providing accurate and efficient analysis.


Features included are as follows:
  • Isotopic abundance based predictions of compound using MALDI MS spectra
  • Generation of calibration model from mixture of analytes
  • Determination of concentration of analytes in complex sample
  • Quantitation based on proton or cation adducts (e.g. M+H, M+Na, M+K, M+Li etc.)
  • Instrument independent input data (both ASCII and mzXML format supported)
  • Additional features like Spectrum viewer, calibration plot viewer and statistical analysis of unknown predictions included
  • JAVA based package, so end user systems' OS independent (supports for Linux, Windows and Mac OS X)
