Empower Tip: Review Window and the Processing Method

The advantage of working with a PDA or a QDa is you can collect data over either a wavelength range or a mass range. Post run you can then decide which 2D channels of data you want to extract and process. There are times when it is easier to work with the 2D data and we can have Empower save the extracted 2D channels for just such a purpose.

We begin by right-clicking on a Sample Set and selecting View As, Channels. Note that all 20 channels are 3D PDA channels.

Take the Sample Set into Review, open and apply the Method Set. In this case we have extracted 280nm.

Go to the Method Set window and check the box which says Save PDA Extracted Channels.

Save the change to the Method Set, close Review and process the Sample Set..

Right click on the Sample Set and select View As, Channels.

We now have both the original 3D data and the 2D data for the extracted wavelength and could then work with either the 3D or 2D data.

It’s that easy!
