How to Process a Calibration with Disabled Points in OpenLab CDS 2.1 to 2.5

Answer

This Information Applies To: OpenLab CDS software versions 2.1 to 2.5

Contents

This article describes how to process a calibration with disabled calibration points in OpenLab CDS software versions 2.1 to 2.5.

Background

In OpenLab CDS software versions from 2.1 to 2.5, every calibration standard injection uses an interim calibration curve.
Amounts in standards and samples are calculated based on those curves. Every injection has its own curve.

Note: For other versions of the software, see the article: How to Process a Calibration with Disabled Points in OpenLab CDS 2.6 or later.

Steps to Follow

1. Right click the calibration point you would like to disable to display a context menu, then select Disable calibration point. (Figure 1)
   
   

   Tips: For further reprocessing sample data, changing to the Processing tab is recommended.

2. The selected calibration point is now disabled. (Figure 2)

3. To requalify sample data with this modified calibration curve, click Requantify Selected and then Save Selected Results. (Figure 3)

   Tips: When you do requantify an unknown sample, select sample from the injection list and disable the calibration point then try requantify tasks.

    

4. Click Print All > Print Selected Injections to print requalified results. (Figure 3, Figure 4)

   Caution: Any disabled calibration points are stored in this session, but not permanently saved within the processing method. If the results set will be reprocessed by clicking Reprocess All, the modified calibration points will be cleared again from disabled to enabled. (Figure 5)
