Tip 38: How to use the retention time (RT) reference peak in an Empower Software Processing Method to address peaks that have been misidentified due to retention time shifts (Part 3).
Tip 37: Working with misidentified chromatographic peaks due to retention time shifts, part 2: The Manually Identify Peaks tool
Tip 36: How to work with chromatographic peaks that have been misidentified due to retention time shifts using Empower Software (Part 1).
Tip 35: How to use the Contour Plot in Empower Software to extract chromatograms and spectra from 3D PDA.
Tip 34: How to extract chromatograms and spectra from 3D PDA data in Empower Software.
Tip #33: How to use an older calibration curve to quantitate samples in Empower Software.
This tip will demonstrate how to overlay a chromatogram at a particular wavelength from two different 3D PDA channels in Empower Software.
How to calculate a chromatogram’s signal-to-noise ratio using Empower Software’s custom calculations feature. (S/N Part 4)
See how to calculate signal-to-noise ratios for pharmacopeial methods where you’re calculating noise from a blank injection. (S/N Part 3)
There are two ways Empower Chromatography Data Software can calculate signal-to-noise (S/N) ratio adhering to the pharmacopeia. This tip will address calculating noise from within the chromatogram. (S/N Part 2)
