Empower Tip: Working with GPC/SEC data in Empower

In this tip, we will continue the discussion about using Custom Fields for GPC/SEC data by looking at the Custom Fields that come with the GPC Default Project. The GPC Default Project is one of a number of default projects that you received with your Empower CDS Software installation.

Let’s see how it’s done!

Copy the eight Custom Fields from the GPC Default project into your own project. These Custom Fields are designed to indicate the molecular weight either above or below a percentage of the distribution as well as the molecular weight at a particular percentage of the distribution.

STEP 2For example, the Mn_above_90pct_of_distr indicates the Mn above 90 percent of the distribution. The numerator of the equation is the sum of the slice areas that meet that criterion. The denominator of the equation is the ratio of slice area to slice molecular weight, for those slices that meet that criterion, and the values for this quotient are then summed.

STEP 3As long as the Slicing table in the Processing Method is populated these values are automatically calculated when the data is processed.

It’s that easy!
