Import 3D Text File

Imports a chromatogram saved in a 3D text file.

A chromatogram in text format may (but need not) contain a heading with a description of the conditions of measurement and must contain data of the chromatographic curve in more columns.

The station automatically interprets the headings of text files exported from the Clarity station and from the EZChrom program.

Note:

The EZChrom ASCII text format uses the file suffix (*.ASC). It differs from the text format exported from Clarity station in the naming of individual items in the heading.

After selecting the chromatograms in the Open Files to Import dialog and pressing the Open button, the Import 3D Text File dialog opens.

The conversion program determines the most suitable import setting according to the content of individual imported text files. Individual settings can subsequently be adjusted in the Import 3D Text File dialog and saved for further use. Import is performed by the OK button.

Note:

If a number of files was selected in the Open Files to Import dialog, a further Import 3D Text File dialog or Import AIA File dialog will open (according to the type of the next selected chromatograms) after clicking on the OK button.

 

Preset

When the same type of files are imported frequently, it can be useful and time-saving to save import settings for further use. In drop-down box on the left user can select from previously saved presets, by clicking button right to list the presets management menu will open. The menu contain commands for saving current setting (Create New...), Rename... or Removepresets. Presets are stored as part of Clarity Desktop settings.

Apply Settings to

This radio button group indicates whether all the settings below will be applied either to current file only or to all files imported at once. In case multiple files are imported at a time, and this radio buttons are set at Current File, the Import Text File dialog will be invoked for every file in the sequel. When Apply Settings to radio button is switched into the All n Files position, subsequent files will be proceeded with the same settings. By checking Prefer Detected Settings checkbox you can force Clarity to use setting detected from the imported file (where applicable).

Apply Method

Choose method whose parameters (integration table, attached calibration, etc.) will be applied into the imported chromatogram. By default, displayed method matches method in the Single Analysis dialog. Leaving this field blank applies default parameters.

Current Text File

The name of imported file including directory path.

Preview

This button will open the current file in simple text viewer. This can help user to identify exact meaning of particular columns when it's not clear from file suffix.

Import From Line

Sets the line of the file on which the data import should start.

Import To Line

Sets the last line of the file that should be imported.

Separator

Selects the sign by which the individual items are separated in the text file. <TAB>, <SPACE>, <COMMA> or <SEMICOLON> are available signs to choose from.

Decimal Separator

Separator of decimal points - <DOT>, <COMMA> or <Windows Locale>. Separator indicated in Windows (as <Windows Locale>) is used as the default.

Note:

Parameters entered to Import From Line, Import To Line, Separator and Decimal Separator fields will be applied on all simultaneously imported chromatograms.

Import Text File

Analyst, Sample ID, Sample, Sample Date, Amount, Dilution, ISTD Amount, Injection Volume

These fields composing the chromatogram heading have the same meaning as described in the chapter "Single Analysis".

Sample Rate

Selects the sampling speed in the number of samples per second (Hz). Select one of the speeds from the list corresponding to the speeds of your A/D converter or enter your own value.

Wavelength

Selects the desired wavelength interval which should be imported.

Signal Multiplier

Selects the units for imported data and factor by which the data should be multiplied.

Signal Axis

Selects the name of the axis.

Save as Chromatogram

Sets the name and location of the resultant chromatogram created after importing a text file. By default, the program will offer to use the original name of the imported file using the suffix *.PRM with a path to the directory of the current project.

To select another name and location for the resultant chromatogram, open the Save As... dialog using the button.

Load Defaults

Selects implicit values of all fields (i.e. returns the dialog into state prior to any changes made after opening).

OK

Confirmation of import.

Skip

Skips current file and proceed to subsequent one while importing multiple files.

Cancel

Cancellation of import.
