We answer a question as a follow-up to Tip #74 on using Empower’s System Suitability option to calculate the ratio of peak to valley height when there’s a valley between the chromatographic peaks; What about calculating valley height when there are two fused peaks?
#69: Learn how Empower Software calculates Peak-to-Peak Noise for USP, EP, and JP Signal-to-Noise calculations.
We begin a multi-part discussion about the System Suitability option in Empower Software, starting with what are Statistical Moments and how are they helpful.
#67: How to save extracted channels after 3D data processing in Empower Software.
#66 This week we will begin a new multi-part discussion around using Method Sets in Empower Software. This post shows how to subtract a 3D baseline from 3D PDA data.
#65: In this final tip in our Deriving Channels series for using Empower Software, we learn about Switch To, a function that you can use to combine data from channels generated by different wavelengths or detectors into one, so that you process a single chromatogram.
#64: How do you look at the second derivative of a chromatogram, which can make it easier to identify coeluting peaks? Neil Lander tackles how to do it in Empower Software.
#63: About once a year our Empower Software product manager, Neil Lander, gets the following question: “Can I create a mirror image of my chromatogram?” The answer is yes, and it’s easy to do.
#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.
#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.
