MassFinder 4: Manual

There are two distinct print dialogs, one for printing labelled chromatograms and the other for printing mass spectra.

Contents

Print dialog for mass spectra

The mass spectra print dialog can be opened by clicking on the print button of the Export MS dialog.

Which mass spectra

The which mass spectra group box inside the print mass spectra dialog lets you decide which mass spectra to print.

You can print out all marked spectra of the current GC/MS run. You may restrict the selecton to only include indentified peaks (marked in yellow or solid blue) or only unknown peaks (marked in red or hollow blue). This functions enables to print collections of mass spectra of all constituents found in a certain run.

Alternatively, you may print the current library hit list, which can be a list of matching library entries or a result list from applying a library filter (parametric retrieval). Thus, you can easily filter the library by any parameters (including all) and print lists of all resulting mass spectra.

The third option simply lets you print the highlighted mass spectrum of the current GC/MS run.

Layout and orientation

The layout and orientation group box lets you select landscape or portrait orientation of the paper. Please note that you do not need to set-up the printer accordingly. MassFinder will overwrite any default printer setting automatically.

The spectra per page settings allows you to select how many mass spectra are to be printed per page. Values 3 to 6 appear to be sensible in most cases.

What data

Tick the checkboxes of the desired data to be printed along with the mass spectrum itself.

The size of structures setting lets you choose between auto-fit and constant bond length.

In auto-fit mode MassFinder will automatically resize all structure graphics, so that all graphics fit into a reasonable bounding box. This is particularly necessary for very large structures. However, the drawback of this mode is that all structures have different bond lengths.

In constant bond length mode MassFinder will choose a standard bond length appropriate for most volatile compounds. The advantage of the mode is that all structures of a page are in harmony and can be compared much easier. However, the drawback is that exceptionally large structures might no fit or overlap with mass spectral signals.

In most cases, the constant bond length mode will produces nicer print-outs. Please try and decide for yourself which mode is more suitable for your requirements.

Printer set-up

The printer set-up button opens a standard Windows printer set-up dialog. Use this dialog to select which printer to use and to configure advanced settings of your printer like duplex.

Do not set portrait or landscape orientation in the printer set-up dialog. MassFinder will overwrite this setting with your selection in the layout and orientation group box as explained above.

Print dialog for chromatograms

The chromatogram print dialog can be opened by clicking on the print button of the Export chromatogram dialog.

Orientation

The orientation group box lets you select landscape or portrait orientation of the paper. Please note that you do not need to set-up the printer accordingly. MassFinder will overwrite any default printer setting automatically.

Options

Please select which acquisition data to print along with the chromatogram profile. Tick the checkboxes accordingly.

The pen width setting allows you to control the line width (pen thickness) of the chromatographic profile. The required value depends on your printers resolution (e.g. 600 dpi or 1200 dpi). Just adjust this value to your requirements.

MassFinder can print any text on the x-axis and y-axis of the chromatographic profile. Tick the checkboxed accordingly and enter the desired axis label text.

Multiple page layout

This feature offers two modes of how to automatically stretch the time axis of chromatograms. Both modes are useful and which mode to use depends on your requirements.

The fit to one or several pages mode lets you select how many pages the selected chromatogram range will cover. MassFinder will stretch the time axis accordingly and all pages will be used completely. This mode avoids almost empty pages with just a few remaining minutes and uses all space available. This is in most cases the mode of choice.

The distribute by time sections mode lets you select how many minutes are printed on each page. MassFinder will stretch the time axis accordingly and print as many pages as necessary in order to print the whole selected time range. This mode is particularly useful if you want to print out several chromatograms which are superimposable and have exactly the same time axis for all runs.

Time range

The time range group box lets you select which time range to print.

You may enter the desired time range manually. Alternatively, you may click on the chromatogram button to tell MassFinder to automatically copy the current time range from the export chromatogram window. You may select the whole run by clicking on the whole chromatogramm button.
