#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.
Tip #49: How to subtract a baseline from a 2D chromatogram by Deriving a Channel (part 3) in Empower Software.
Tip #48: Learn how to correct for the time offset between detectors that are connected in series by Deriving a Channel in Empower Software. (Part 2)
Tip #47: Smoothing a channel of chromatographic data collected with a UV detector through Empower Software’s Deriving Channels feature.
Tip #46: Recently I’ve had several questions about how baselines are determined using Empower Software’s ApexTrack peak integration algorithm. Let’s take a look at how they work.
