MassWorks Version 5.0

Version 5.0

Now Shipping!

Adding to the legacy established in previous versions, MassWorks 5.0 is still the easy-to-use post acquisition software package that utilizes Cerno’s patented TrueCal™ technology to achieve high mass accuracy and high Spectral Accuracy and enable elemental composition determination on conventional mass spectrometers of unit mass resolution using the patented CLIPS formula search.  MassWorks sCLIPS and BestScan sCLIPS now also provide high spectral accuracy through exact line-shape calibration without the need for standards. MassWorks integrates the powerful TrueCal calibration technology to obtain up to 100X improvement in mass accuracy on unit resolution systems and up to 99.9% spectral accuracy on both high and unit resolution systems in a fast and versatile MS application software package. By mass accuracy with Spectral Accuracy, Cerno methodologies can provide significant improvements to all types of MS data, both high and low resolution.

  • High mass accuracy on quadrupole GC or LC/MS (up to 0.005Da)
  • Improved Spectral Accuracy on all systems (up to 99.9%)
  • Elemental composition determination on quadrupoles
  • Eliminating up to 95-99% of incorrect elemental compositions on high resolution MS
  • Accurate isotope fine structure analysis on ultra-high resolution MS
  • Direct and accurate analysis of unresolved mixtures, e.g.,isotope labeling and biologics modifications

MassWorks now includes sCLIPS and Best Scan sCLIPS, for improving formula ID on high resolution MS, and CLIPS, for enabling formula ID on unit resolution GC or LC/MS single or triple quadrupoles.

New features for Version 5.0

  • NIST Library Search  and ChemSpider Integration

The power of GC/MS search coupled with accurate mass (>±10mDa) search and better than 99% spectral accuracy turns your single quad GC/MS into a powerful problem solving analytical tool.  Perform accurate mass searches in the NIST library by simply clicking on the spectrum in MassWorks.  Verify the library hit with increased confidence using the power of spectral accuracy and the built-in CLIPS formula search. Search formulas from the CLIPS hit list in either NIST or ChemSpider libraries to confirm the compounds and explore their possible structures and other molecular properties.

  • BestScan™ sCLIPS

High resolution traps, such as the Orbitrap, can suffer from poor spectral accuracy due to space charge effects even with automatic gain control.  MassWorks identifies the best spectrum across the eluting chromatographic peak using Spectral Accuracy to minimize this problem by pinpointing the best MS scan, typically not at or near the chromatographic peak apex, to use for accurate elemental composition determination of unknown compounds.

  • "The accurate mass profile extract ion chromatogram (AMPXIC) obtained through accurate mass measurement and isotope profile-mode filtering [performed with MassWorks] eliminated the false positive peaks observed using conventional XIC in the metabolite profile."  - Click here to read full presentation

  • "I have tested and used the MassWorks software since the summer of 2007. The main purpose for me is using its formula ID feature to confirm the GC/MS NIST library search results for unknown chemical substance identification especially when the [NIST] search match values are similar for more than one compounds. The software is relatively simple to use and most times provides the #1 match for our testing chemicals with more than 200 compounds in a variety of chemical groups."

  • "Starting a little bit "speechless" from our side your Presentation helped really changing our mindset, from "unbelieving" into "believer". After this Test with a sample taken from real life with real interferences my colleagues and I fully agree that MassWorks is indeed a powerful tool for advanced GC/MS analysis. We found that MassWorks is really a "must have" product for us..."
    Researcher from a large German chemical company
  • "With PFTBA calibration performed to each GC/MS run, mass accuracy better than 10mDa can be achieved and Spectral Accuracy of better than 99% can be achieved to help attain reliable formula determination. The mass calibration is stable after 11 days without significantly compromising formula determination. While mass calibration is more susceptible to time related variations, the Spectral Accuracy has been shown to be robust enough for formula determination after 19 days." -Click here to read full presentation
