MassFinder 4: Manual

The Export MS dialog focuses on export capabilities of mass spectra in a variety of formats:

  • high-quality, scalable graphic (Windows enhanced meta file format)
  • classical m/z mass list of the labelled peaks for publications
  • Excel table including all ions and abundancies for further processing
  • SVG graphic for display in any internet browser or wiki


Selecting GC/MS or library spectrum

Graphical options

Image:Tutorial-Buttons-GraphicalOptions.png The first button allows selection of thin or thick lines to be used. For Microsoft Word or any other printing purposes we recommend to use thin lines, while some Powerpoint presentations profit from thicker lines.

The next three buttons let you show or hide the peak labels, mass axis labels and abundance axis labels. The structure button shows or hides the chemical structure associated to library entries (no function if applied on mass spectra of GC/MS scans).

The title button shows or hides the chemical name in the upper left corner of the mass spectrum.

Font and Color

MassFinder offers a variety of graphical and text based output formats. If you require any other export format, please do not hesitate to contact us. Most wishes we can realise either free of charge or for a nominal fee.

Clipboard graphic

Image:Tutorial-Buttons-ExportGraphic.png Export the current view to the clipboard. MassFinder exports the graphic in a scalable vector format (Windows enhanced metafile, *.emf) that can be resized and processed by other applications such as Microsoft Word, Microsoft Powerpoint or Adobe Illustrator.

Please adjust the size and aspect ratio of the export mass spectrum dialog window in order to set the size of the exported graphic. You can leave and re-enter the dialog and MassFinder will keep the size, so that you can export several mass spectra in exactly identical dimensions. The status line at the bottom shows the size of the graphic in pixel.

Excel table

Image:Tutorial-Buttons-ExportExcel.png Export the current mass spectrum in Excel table format to the clipboard. The exported table contains all ions, intensities and abundancies and can be used to reconstruct the exact mass spectrum or to import the mass spectrum into other software systems.

SVG graphic

Image:Tutorial-Buttons-SVG.png Export the current mass spectrum in SVG format to the clipboard. This format is used to present mass spectra on websites and wiki sites. Most modern internet browsers can display SVG files without additional plug-ins.

Export as m/z mass list

At the bottom of the dialog MassFinder lists all labelled peaks as m/z list.

Please select the sort order of the mass signals, i.e. abundance decreasing, mass decreasing, mass increasing. Then click on the copy clipboard button to export the m/z list.

This format is perfectly suited for preparing scientific publications or Ph.D. theses. Please note that you can add or delete each single label (see next chapter) and each change will take effect automatically both in the graphical mass spectrum as well as in the m/z list.

Customised labels

Please hold the shift key down and click with the left mouse button on the top of any signal. MassFinder will toggle the label on/off. Thus, you can delete existing labels or add new labels.


Image:Tutorial-Buttons-Print.png The print button will open the print dialog.

The print dialog offers high-quality printing of single mass spectra or of all marked peaks or the complete library hit list, which may be library matches or search filter results.
