Issue Description

Adding duplicate standard samples to an existing results table in the Analytics mode of Sciex OS software generates the following error: "Incorrect Argument. An item with the same key has already been added."

User-added image

This error was generated after the following steps were completed: 

  1. A batch was built in SCIEX OS software where the standard samples were labeled as standard in the Sample Type field. 
  2. The same standard samples were added elsewhere in the same batch by copying and pasting them into the batch table. 
  3. The samples in the batch were submitted and acquired.

Resolution

This is currently a limitation of the SCIEX OS software, whereby the incorrect argument error will be generated when the same set of standard samples appears multiple times in the same batch.

The workaround is to submit the calibrator samples only one time with the label of sample type, standard; if the calibrators are added again in the same batch, then the repeated samples should have their sample type changed to unknown prior to batch submission. 

After data is acquired, these injections can be used to create a results table in SCIEX OS software. There has been no issue with changing their sample type from unknown to standard and then entering the quantitation information at that time.
