WebAug 28, 2014 · Aug 28 2014. The aim in high performance liquid chromatography (HPLC) and gas chromatography (GC) is to get good peak shape and good separation. The most desirable outcome is the … WebSometimes chromatogram is obtained as in fig. 1. The separation is very good, but the base line shows “spikes”. Such a spike is not a problem if it happens on the base line, but if a peak elutes, the spike can cause a wrong value and the analysis has to be repeated. Spikes are electrical signals (pulses), that are initiated by an external event.

When you are examining the results from your chromatography, you are hoping for well-defined peaks that are easy to read, and also symmetrical. This means that you know exactly what kind of material you are dealing with, and can plan how this material will be handledaccordingly. However, this might not … See more Tailing is basically the inverse of fronting. The peak is presented asymmetrically, with a broader second half and a narrower first half – breaking away from the ideal peak shape, with its … See more Ghost peaks refer to the residual images of peaks that appear during an experiment but are unrelated to the experiment itself. For example, maybe your original hypothesis predicts that you will see A, B, and C peaks in your … See more We have already discussed how, in order to get a solid set of result, chromatogram peaks need to be well-defined.
