Tip #244: Method Versioning: Method Validation Protocols and Processing Methods

Welcome back to Get Empowered! In the last Empower tip-of-the-week blog for Empower Chromatography Data System, we learned about Method Versioning as it applies to Sample Set Methods (Tip #243).

In this week’s tip, we continue the series on Method Versioning, focusing on Method Validation Protocols and Processing Methods.

Let’s get started.


Modifying a Method Validation Protocol via the Method Validation Study

Step 1

The current Method Version for ‘AAA Validation’ is 1 (figure 1).

Figure 1

Step 2

Open the Validation Study and modify the Protocol by enabling ‘System Precision’. Save the change (figure 2).

Figure 2

Step 3

In Method Properties, Method Version 5 of the Validation Protocol has been created. Highlight ‘Method Version 5’ and ‘Method Version 1’. Click ‘Differences’ (figure 3).

Figure 3

Step 4

The difference between the two versions is the enabling of System Precision (figure 4).

Step 5

Method Version 1 remains the current version in the project window (figure 5).

Step 6

Right click on the Validation Protocol, open and make a change, such as disabling System Precision (figure 6).

Step 7

Method Version 6 of the Validation Protocol is now the current version (figure 7).

Step 8

Processing Method ‘19Jul’ is at Method Version 1 (figure 8).

Step 9

Make a change to the method, in this example the Touchdown % is modified. Save with the same name. The current Method Version is now ‘Method Version 2’ (figure 9).

Figure 9

Step 10

Method Differences displays the change in Touchdown % (figure 10).

Figure 10

Step 11

Take a result generated with ‘Method Version 1’ of the Processing Method into Review, note the Touchdown % is ‘0.100’ (figure 11).

Figure 11

Step 12

From the ‘File’ menu, select ‘Save As Processing Method’ keeping the same name which results in Method Version 3 as the current version (figure 12).

Figure 12

Step 13

Method Differences shows that ‘Method Version 3’ is back to the original value for Touchdown % as it was in ‘Method Version 1’ (figure 13).

Figure 13

It’s that easy!


Final Note: This can be done with either the Pro or QuickStart interface.
