Injection List

Instrument name

Name of the instrument with which the data has been acquired. The instrument name is available for data acquired and saved with OpenLab CDS 2.6 or higher. It may not be available for older data.

Order #

Order number of the sample in the sequence (sequence line).

Injection #

Injection # of total number of injections per sample.

Sample name

Sample name of the injection as entered in the sequence.

Sample label

Sample label of the injection (optional). Can be used, for example, to search for data in the Data Selection view, or to group data in a report template. Only alphanumeric characters are allowed.

Sample type

Sample types are used in a sequence to describe each item being processed.

Sample type descriptions:

• Sample - A sample with unknown amounts of analytes being analyzed.

• Blank - A sample without any analytes that is treated like a sample. It is used as a signal-to-noise reference for all subsequent samples and for system suitability. If an ISTD method is being used, then the Blank usually contains the internal standard.

• Double Blank - Sometimes called solvent blank, it is used to prove that no chromatographic artifacts are coming from the instrument flow path for that particular column.

• Cal. Std. (Calibration standard) - A sample with a known amount of analyte that is used as a reference to create or update a calibration table in the processing method.

• QC Check - A sample with a known amount of analyte that is used to verify and prove that the calibration is correct.

• Spike - A sample with a known amount of standard added.

• Sys. Suit. - A sample that is run to demonstrate that system is working correctly as expected. This sample is typically run before running other samples.

Bracket

Shows how calibration standards are bracketed according to the selected Bracketing mode.

Run type

For calibration standards:

• Clear all calibration means that all previous calibration points will be removed when processing this standard.

• Clear calibration at level means that all previous calibration points of the level of the calibration standard will be removed when processing this standard.

• Empty means that a new point will be added to the calibration curve. If a calibration point already exists for the current calibration level, and you use average values to calculate the calibration curve, the application calculates the average value of all existing calibration points for the given level (see Modes of using individual points).

Level

For calibration standards: level of the standard.

Injection date

Date and time when the sample was injected.

Modification date

Date when the injection was last processed.

Sample Amount

Sample amount as entered in the sequence.

ISTD Amt 1-5

ISTD amount as entered in the sequence table, but can be modified for a single injection afterwards.

Multiplier 1-5

Multiplication factors as entered in the sequence table per sample, can be modified for a single injection afterwards. Used to calculate the concentration for all compounds (see Concentration and mass%)

Dil. Factor 1-5

Dilution factors as entered in the sequence table per sample, can be modified for a single injection afterwards. Used to calculate concentration for all compounds (see Concentration and mass%)

Acq. method

Name of the method used to acquire the raw data (acquisition method).

Proc. method

Name of the method used to analyze the data (processing method).

Description

Description of the sample as entered in the sequence table.

Vial

Vial number or plate location.

Injector position

Position of the injector on the instrument. For dual tower GC instruments: front or back. For LC: always front.

Data file

Name of the data file if source system is file based.

LIMS ID 1-3

Keys required for connection from and to a LIM system.

Barcode

Barcode label as it has been read from the sample vial. The value is read only, as it is intended only for automation purposes.

Expected Barcode

The expected barcode is entered manually in Acquisition. When you automate your processes, you can determine actions if the expected barcode does not match the actual barcode (e.g. abort the sequence). The value is read only, as it is intended only for automation purposes.

Compound amounts

Indicator if the amount of a calibration sample has been modified. The compound amount is defined in the calibration parameters in the method, but may be adjusted for individual injections.

When clicking in the Compound amounts column of a calibration standard, part of the window shows the actual amounts in the sample and the amounts defined in the method.

Target 1-5

For mass spectrometry: Masses or formulas that you want to use for the MS sample purity calculation. You can mix molecular weights and formulas, for example: . The targets may already be set in Acquisition, but can be adjusted here.

If you add target masses or formulae, and you link your injection to a mass spectrometry method, the processing function will automatically generate extracted ion chromatograms (EICs). If the target masses correspond to any available selected ions, it will also extract selected ion monitoring (SIM) signals.

Compound custom fields

If you have configured Compound Custom Parameters for your project: Click in the Compound custom fields column to show the corresponding parameters and values in a separate part of the window.

If you have configured Sample Custom Parameters for your project, there will be a separate column for each single parameter.

Compound custom fields are configured per project in the Control Panel. There you also define if a custom parameter is mandatory. Values of mandatory parameters cannot be deleted. Parameter values can also be modified in Acquisition.

Blank

Select which blank to subtract from the signal of an injection (see Configure blank subtraction). By default, the blank last acquired prior to the injection is selected.

The blank can only be selected if:

• Blank subtraction is turned on in the processing method

• The sample is not a blank itself

• The option Use blanks defined in the sequence is selected in the processing method
