AIA

The AIA file format has relatively strictly designed form, but not the content. Thus, an AIA file may contain various custom items. The dialog for importing files in AIA format is designed as an expandable tree, making it easier to view items contained in the imported file.

Import AIA File

Preset

Allows to select a preset from the list of stored import presets. A preset can be created / deleted / managed using the button.

Apply Setting to

Radio-button deciding whether the settings for the import will be applied just to Current File selected (the one as defined by the AIA File/File field) or to All n Files selected for import (if multiple are selected).

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.

AIA File

Name of the imported file including directory path.

Window with parameters

Items found in the current AIA file and their parameters. Expand collapsed items by clicking the “+” sign with the left mouse button (similar to working with the Explorer application in Windows).

Clarity will correctly import only files with following parameters:

uniform_sampling_flag = Y

actual_sampling_interval value set

detector_maximum_value < 10¹²

detector_minimum_value > -10¹²

Override detected values

Allows to override or fill in the missing value of selected parameters stored in AIA files, thus allowing to import chromatograms exported without required values.

Each parameter values are automatically detected from selected AIA file.

detector_unit (required)

Determines the units in which the signal values are stated.

retention_unit (required)

Determines the units in which time values are stated.

Recognized values are following:

• miliseconds, milesecond, ms
• seconds, second, sec, s
• minutes, minute, min, m

In case of improper values, seconds will be used as time unit.

uniform_sampling_flag (required)

Determines the uniform sampling.

Uniform sampling flag has to be set to Y (=Yes).

Clarity supports only data with equidistant time spacing. Importing AIA file with non-equidistant data time axis will be deformed.

detector_maximum_value & detector_minimum_value

Sets the range of detector signal.

Y multiplier

Sets the multiplier for scaling the data on the signal axis.

Chromatogram

Name and location of the resultant chromatogram created after importing an AIA file. By design, the program will store the original name of the imported file along with the *.PRM suffix and the path to the directory of the current project.

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