#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.
A thousand small delays and opportunities for error can snowball over the years of a complex biotherapeutic drug development program. They add up to lost time and increased risk in an endeavor that has little tolerance for either. It doesn’t have to be this way.
#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.
On the impact of retentivity and characteristics of the stationary phases for reversed-phase proteomic separations and how you can use them to your advantage.
Removing the ability for individual users to either delete data or to disable audit trails is expected to be both implemented and validated for data integrity. But when changes are required, what editing tools should be accessible to an analyst?
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.
