#57: How to derive a channel in Empower Software when working with 3D mass spec (MS) data, or the Total Ion Chromatogram (TIC), which plots the sum of all ion intensities acquired across the mass range at every time point.
#56: If you have an ACQUITY QDa Mass Detector on your HPLC or UPLC instrument and collect 3D MS data, there are a number of options for deriving a channel. In today’s tip, we’ll discuss deriving Single Mass from 3D MS data.
#55: Have you ever had a sample where each component had a different lambda max and it was difficult to pick one wavelength to use for quantitation? We show how to use Timed Wavelength when Deriving Channels in Empower Software.
#54: We discuss another option for Deriving Channels in Empower Software when working with photodiode array (PDA) data, called RatioPlot.
#53: In this tip, we will discuss another option for Deriving Channels when working with PDA data, called TotalPlot.
#52: We discuss the options for Deriving Channels when working with PDA data, focusing on MaxPlot: A 2D chromatogram that plots each time point at the maximum absorbance across the wavelength range.
Tip #51: How do I subtract a baseline at a particular wavelength from my PDA data? More info on Deriving Channels in Empower Software.
