Q&A time: What is acrylamide? How dangerous is it? How do food testing laboratories detect it?
#62: In Empower Software, deriving a channel lets us mathematically combine two channels of data. What if we wanted to combine more than two channels? There’s a relatively new feature that lets us combine up to 10 channels of data, called Formula Based Derived Channel. Let’s see how it works.
Can pairing column stationary phases improve nanoflow and microflow LC-MS results? Let’s take a closer look at the basics of trapping and the advantages and considerations for implementing a trapping step in a LC separation in part 1 of this 3-part series.
#61: Learn how to derive a channel for Timed Mass for 3D MS data in Empower Software. Timed Mass creates a channel that specifies a mass at specified starting times, which can maximize sensitivity and allow us to perform quantification for all components regardless of the differences in mass.
Is your analytical method bound for the lab down the hall, or the lab halfway around the world? If you’re an analytical or QC scientist, get ready for more method transfers between organizations. We explore the complexities of analytical method transfer in part 2 of our ongoing series.
#60. Another option for Deriving Channels in Empower when working with 3D MS data is Total Plot, a 2D chromatogram that plots the sum of all ion intensities acquired across a specified mass range at every time point. It is a subset of the TIC plot, which we covered in Tip 57.
#59: We previously discussed MaxPlot for 3D PDA data in Tip 52. Today we are going to learn about MaxPlot for 3D MS data. MaxPlot is a 2D chromatogram that plots each time point at the maximum intensity across the mass range.
