Use of Empower's Distribution table when performing GPC/SEC - Tip305
Article number: 249482
OBJECTIVE or GOAL
Automatically calculate the percent areas of specific molecular weight slice ranges from the Distribution table.
ENVIRONMENT
- Empower
- Tip of the Week #305
PROCEDURE
STEP 1
The example has six ranges (Figure 1).
STEP 2
Create one peak Custom Field to calculate the % Area per slice range (Figure 2).
STEP 3
The expanded formula is shown as specified. Depending on how many ranges you want to be calculated, you could use the CConst fields found on the slicing tab of the Processing Method (Figure 3).
STEP 4
Finally, add these fields to the report. In this example, We create three custom fields for three ranges, and the values add up to 100 as they should (Figure 4).
ADDITIONAL INFORMATION
This can be done with either the Pro or QuickStart interface.
