WebNov 3, 2024 · LC-MS/MS Separation of 38 Amino Acids in HILIC Mode In this application, amino acids separation challenges were overcome by combining the separation power of the bioZen Glycan HILIC phase LC column with SWATH® Acquisition, resulting in highly reproducible resolution and accurate quantitation and confirmation of 38 amino acids. … WebNow, let’s look at the results. Figure 3 shows the LC-MS/MS separation of glyphosate, AMPA, and glufosinate on a short hybrid ion-exchange/HILIC column (the dimensions are 2.1 x 30 mm, 2.7 µm superficially porous particle). As you can see, we have reduced the cycle time to a mere 8 minutes with excellent retention, resolution, and peak shape.
