Dictionary of fields used in 2D-LC

In addition to the fields listed under Fields used in OpenLab CDS, the following fields are available for 2D data:


Signal

Reporting parameter

Custom Calculation parameter

Shown in Data Analysis

Description

Signal_CustomFields: 2DLC_CutNumber

n/a

Sampling Table - Cut #

or

Peak Table ²D - Cut #

Contains the cut # of a ²D peak (for cut signals)

Signal_Tags

n/a

n/a

Additional information on the type of 2D signal ("2DLC_CutSignal" or "2DLC_Full2DSignal").

Signal_Dimension

Signal_Dimension

n/a

Defines on which detector the signal was acquired in a 2D-LC setup (1 or 2).


Cut

The values that are shown in the Sampling Table window are available in the Sampling Table snippet. There are no individual reporting parameters or custom calculation parameters.


Compound

Reporting parameter

Custom Calculation parameter

Shown in Data Analysis

Description

Compound_CorrExpRetTime2D

Compound_CorrectedExpectedRetentionTime2D

Injection Results - Corr. expected ²D RT (min)

Corrected expected ²D retention time of the 2D peak. Time unit: minutes

Compound_ExpectedRetTime2D

Compound_ExpectedRetentionTime2D

Injection Results - Expected ²D RT (min)

Expected ²D retention time of the 2D peak. Time unit: minutes

n/a

Compound_Dimension

Processing method - Type

shows if the compound is from a 1st or 2nd dimension detector. Returns the value 2 for two-dimensional compounds.


Peak

Table: Peak

Reporting parameter

Custom Calculation parameter

Shown in Data Analysis

Description

Peak_RetentionTime

Peak_RetentionTime

Injection Results - ¹D RT (min)

Retention time of the ¹D peak. Time unit: minutes

Peak_RetentionTime_2D

Peak_RetentionTime2D

Injection Results - ²D RT (min)

²D retention time of the 2D peak (weighted average by area, see Properties of a 2D peak. Time unit: minutes

Peak_RelativeRetTime

Peak_RelativeRetentionTime

Injection Results - RRT

Relative time (¹D) to the reference peak

Peak_RelativeRetTime_2D

Peak_RelativeRetentionTime2D

Injection Results - ²D RRT

Relative time (²D) to the reference peak

See Calculations for relative retention times in 2 dimensions

Peak_CustomFields: 2DLC_2DPeakId

n/a

n/a

ID of the 2D peak that is associated with a ²D peak (each ²D peak belongs to one 2D peak; each 2D peak is made of one or several ²D peaks). This value is not visible in the user interface. It is used in the 2D-LC custom assembly.

Peak_CustomFields: 2DLC_2DPeak_StartTime_1D

n/a

X-axis in the Contour Plot 2D

Start time of the cut of the first ²D peak belonging to the 2D peak

Peak_CustomFields: 2DLC_2DPeak_EndTime_1D

n/a

X-axis in the Contour Plot 2D

End time of the cut of the last ²D peak belonging to the 2D peak

Peak_CustomFields: 2DLC_2DPeak_StartTime_2D

n/a

Y-axis in the contour plot

Earliest start time of all ²D peaks belonging to the 2D peak

Peak_CustomFields: 2DLC_2DPeak_EndTime_2D

n/a

Y-axis in the contour plot

Latest end time of all ²D peaks belonging to the 2D peak

Culture information


The start and end times saved in these custom fields are culture-independent. To apply the local culture settings in a report template, use the function ConvertDoubleToCurrentCulture. The function belongs to the following class of the 2D-LC custom assembly: Agilent.Chromatography.Mdlc.DA.ReportingDataProvider.CustomAssembly.CompoundsAndPeaksMethods

Expression example: =Code.Methods2DLC.ConvertDoubleToCurrentCulture(CFE((Peak_CustomFields),"2DLC_2DPeak_StartTime_2D"))

This custom assembly is used, for example, in the report template 2DLC_Single_Injection_Compounds_Report.
