Now let’s revisit some questions submitted by readers.

QUESTION 1

How is Vial ID generated and explain instances where the Vial ID changes.

You can create a View Filter on either the Injections tab or Channels tab of the Project window which displays Vial ID. When does the Vial ID get created?

If we create or load an existing Sample Set Method into the Run Samples window and then collect the data, we will generate a Sample Set.

If we view the Sample Set as Channels we see the Injection ID, the Channel ID, and the Vial ID.

The Vial ID is associated with a row in the Sample Set. If we make any changes to the Sample rows in Alter Sample, then the Vial ID will change. In this example, we changed the Sample Weight for all samples from 1 to 10.

Once those changes are saved, we now see that the Vial Id has been updated for the Samples in this Sample Set.

QUESTION 2

Is it normal for my blank to be flagged when a Must Peak is absent?

This Sample Set has a blank, injected three times.

On the Component tab of the Processing Method, Peak A is selected as a Must Peak. This means that Peak A must be found in every chromatogram.

Peak A is not found in the blank, therefore, the Result is flagged as Faulted and Result Code F01 is displayed.

A similar situation is observed if an Internal Standard peak, a Default peak and/or an RT Reference peak is missing. Like a Must Peak, these types of peaks must also be present in every chromatogram. The online Help defines the Result Codes that indicate if one of these peaks is missing.

In answer to this question, it is normal behavior if a blank is flagged due to a missing Must Peak, Default Peak, Internal Standard Peak or RT Reference Peak.

It’s that easy!
