Software for high accuracy data from any mass spec
Cerno Bioscience's MassWorks is post acquisition software that utilises patented MSIntegrity technology to achieve high mass accuracy even on conventional mass spectrometers of unit mass resolution

In addition, the enhancement in signal-to-noise provided by the software can significantly lower the detection limits for compounds measured at trace levels.
The application note describes how elemental composition analysis can typically only be achieved using higher resolution systems, which can incur a much higher cost.
MassWorks is an exciting development for elemental analysis, as it enables identification of unknown compounds even when using a low resolution instrument.
With this software, a tandem MS capability is unnecessary, as formula ID is accomplished in the full MS scan mode.
Massworks is now available with Clips (calibrated lineshape isotope profile search), which provides dramatically improved results for formula ID.
The Clips algorithm provides a unique level of accuracy by matching each formula candidate to the carefully calibrated mass spectrum in profile mode.
This enables highly accurate results at a lower cost, using a lower resolution system.
The easy-to-use post acquisition software package utilises Cerno's patented MSIntegrity technology to achieve high mass accuracy, offering elemental analysts substantially improved and accurate measurements utilising their existing mass spectrometer instruments.
This means that they are able to achieve the results of a high-end spectrometer for a fraction of the investment.
MassWorks is capable of the analysis of complex samples with substantial chemical backgrounds as well as that of unknown compound samples which require identification.
MassWorks also benefits from Cerno's DirectRead technology to interpret most instrument data formats directly, eliminating the need for importing or exporting MS data to the clipboard or utilising intermediate exchange formats.
This saves time, reduces transcription errors, simplifies file management, and saves substantial disk space.
As DirectRead doesn't alter the original data, it assists compliance with common regulatory requirements such as GLP.
