Learn how to address common peak shape challenges in HPLC analyses, including peak shape changes with sample groups, used columns, or increased injection volume, with this primer guide
Direct Manufacturer Peak Tailing in GC Systems
Peak tailing is present in a chromatography peak when it has an excessive asymmetry with a trailing edge. A normal peak is almost symmetrical. Other chromatographic problems are
Direct Manufacturer Tail-producing slow adsorption—desorption process in liquid—solid
The tailing peak shape observed in liquid—solid chromatography is analysed on the basis of the assumption that peak tailing at high solute dilution is a kinetic effect of slow
Direct Manufacturer Troubleshooting Problems with Peak Shape (Peak Tailing
High-Performance Liquid Chromatography (HPLC) is a widely used analytical technique that separates and quantifies compounds in a mixture. One critical aspect of HPLC analysis is the
Direct Manufacturer Fixing GC Peak Tailing for Cleaner Results | Separation

Direct Manufacturer What Causes Peak Tailing in HPLC?
What Causes Peak Tailing in HPLC? By Chrom Tech – Your Chromatography Consumables Partner Since 1983 Understanding Peak Tailing
Direct Manufacturer Troubleshooting Basics, Part IV: Peak Shape Problems
The ideal chromatographic peak will have a Gaussian shape, but it is rare that a perfectly symmetric peak is observed in real chromatograms. Most peaks tail slightly, and as the column ages,
Direct Manufacturer Why Do Peaks Tail?
A peak is labelled as tailing or asymmetrical when it deviates from the ideal, symmetrical shape of a Gaussian peak. Figure 1 shows an example of a tailing peak.
Direct Manufacturer The perfect peak shape: Five solutions to peak tailing
Read on to find out more about perfectly symmetrical chromatography peaks and five ways to achieve them by avoiding peak tailing. My wife and I were out for a stroll
Direct Manufacturer Why Do Peaks Tail?
If you look carefully, you will see that almost every chromatographic peak tails to a certain degree. Although many of today''s liquid chromatography (LC) columns are less problematic from this
Direct Manufacturer Total peak shape analysis: detection and quantitation of concurrent
Two simple graphical approaches are presented to analyze peak shapes typically observed in gas, liquid, and supercritical fluid chromatography as well as capillary electrophoresis.
