How to Identify an Unknown GC/MS Peak and Estimate Its Concentration | MSD Data Analysis
An unknown GC/MS peak becomes much more useful once you can determine what it may be and estimate how much is present. In this video, I show how I work through an unknown peak in MSD data. I cover: • Selecting the unknown chromatographic peak • Reviewing the mass spectrum • Using a library search for tentative identification • Evaluating the library match • Comparing the unknown response to a known compound • Estimating the unknown compound concentration from the response Lib
