Tip #233: Adding Peak Names to Molecular Weight Standards when Performing GPC
Welcome back to Get Empowered! In the last Empower tip-of-the-week blog for Empower Chromatography Data System, we learned how to quantitate a peak at one wavelength using a calibration curve for a different peak at another wavelength with data collected using the PDA detector (Tip #232).
In this week’s tip, we will learn how to add peak names to molecular weight standards when performing Gel Permeation Chromatography (GPC).
Let’s get started.
In either Alter Sample or Run Samples, click the ‘Amount’ tool to open the ‘Component Editor’ (figure 1).
On the ‘Mol Weights’ tab for the current sample, enter the peak names into the ‘Type’ field [NOTE: you can click ‘Next’ if you have multiple standards to continue entering names] (figure 2).
Once you open the Processing Method, click ‘Integrate’ followed by ‘Calibrate or Process the Data.’ The ‘Name’ field in the Peaks table is now populated (figure 3).
To add peak names to the chromatogram, right-click on the chromatogram and select ‘Properties’. Deselect ‘Use MP instead of Name’ and then select ‘Name’ for one of the labels (figure 4).
It’s that easy!
Final Note: You can use either the Pro or QuickStart interface for this tip.
