Spectra (3D)/Scans (Agilent LC System)
The table on this tab page shows the spectra (3D) signals provided by the Instrument Control Framework (ICF) and their assignment to the corresponding Chromeleon channels. Usually, the signals/channel assignment is performed automatically by Chromeleon. However, when configuring module clusters or if your system contains modules that are not yet known by Chromeleon, the signal settings have to be adapted manually. In this case, verify correct configuration of the options described below. In particular, make sure that
the signal assignment is correct. Note that each available ICF signal must be assigned to a Chromeleon channel. Otherwise, loss of data will result when acquiring data for a specific channel.
the naming of Chromeleon channels is correct
the correct upper/lower limits for each signal channel are specified. For information about suitable lower and upper limit values, refer to the operating manual of the respective module.
the appropriate unit and correct factor are used
If multiple DAD detectors are installed, only one 3D channel per timebase and only the channel of the first DAD can be recorded. For any other DAD, 2D and single scan data can be recorded.
Recording of 3D data using an FLD is not supported. However, recording of 2D data is possible.
Tips:
Incorrect entries are indicated by a red error icon displayed in front of the respective line. In case of an error, the OK button is disabled and you will not be able to continue until all errors have been resolved.
Warnings are highlighted by a yellow background and indicate inconsistencies, for example in units, between the Chromeleon and ICF signals. Check the table carefully for any warnings, especially for signals of the generic (Gen) signal type.

Description |
|
|
|
|
Enabled |
Select a check box to enable the related signal or channel. Data can be recorded only for the selected signals (channels). If a check box is cleared, the signal (channel) will not be available in Chromeleon. |
|
|
|
|
Type |
Indicates the type of the signal. |
|
|
|
|
Name |
Specifies the name of the Chromeleon channel that is assigned to the corresponding ICF spectrum signal. You are free to select any signal name. However, make sure that the name is unique. All signals used in a timebase must have different names. Valid characters for a channel name are the letters A-Z, numbers, percent symbol, and underscore, the maximum number of characters is 24. |

Spectrum Signal |
Indicates the name of the spectrum signal provided by the ICF. |
|
|
|
|
Min./Max Value |
Specify the lower/upper limits for the respective signal channel. |
|
|
|
|
Unit |
Specify the signal unit for the recorded data, for example, µS, nA, mAU, °C. To change the unit, overwrite it directly in the field. A changed unit is indicated by a yellow background color. |

|
Factor |
Specify the factor for the selected signal (channel). |
