Tailing peaks are a known problem in chromatography (both HPLC and GC). It means the analytes are experiencing an out-drawn (extended) retention time and is usually due to one of these factors:
- Contaminated or active injector liner, seal or column
- Dead volume due to poorly installed liner or column
- Ragged column end
- A bad match between the polarities of the stationary phase and the solvent
- A cold region in the sample flow path (GC)
- Debris in the liner or column
- Injection takes too long
- Split ratio is too low (GC)
- Overloading the inlet
- Some types of compounds such as alcoholic amines, primary and secondary amines and carboxylic acids tend to tail
Tailing in chromatography refers to the phenomenon where the peak in the chromatogram is elongated on one side, leading to a distorted peak shape. This can be caused by factors such as non-ideal interactions between the analyte and the stationary phase, resulting in slower elution. Tailing can affect the accuracy and precision of peak identification and quantification in chromatographic analysis.

What are the causes of tailing in chromatography?
Tailing in chromatography can be caused by factors such as non-specific interactions between the analyte and the stationary phase, column overload, sample matrix effects, or inaccuracies in the injection process. These factors can lead to peak distortion, decreased resolution, and decreased sensitivity in chromatographic separations.
What is meant by tailing a spot in Chromatography?
Tailing in chromatography refers to a peak shape that has a gradual slope on the downside of the peak, resembling a tail. This can be caused by interactions between the analyte and the stationary phase, leading to slower elution. Tailing peaks can affect resolution and accuracy of the analysis.
What are the different types of chromatography?
The main types of chromatography include gas chromatography (GC), liquid chromatography (LC), thin-layer chromatography (TLC), and high-performance liquid chromatography (HPLC). Each type of chromatography separates compounds based on their differing affinities for a mobile phase and a stationary phase.
How many types of Chromatography are there?
There are four main types of chromatography: gas chromatography (GC), liquid chromatography (LC), thin-layer chromatography (TLC), and high-performance liquid chromatography (HPLC). Each type of chromatography has specific applications and uses in separating and analyzing chemical compounds.
How is paper chromatography used in everyday life?
it can be used in everyday life by liquid chromatography, gas chromatography, thin-layer chromatographyand paper chromatography.

How did the miners dispose waste?
A ditch is made beside a tree and the tailing is dumped into it, and then, the tailing is covered with earth. This method is known as Phytostabilisation.
Do tailing ponds evaborate?
That's a terrible question. Of course tailing ponds evaporate. Use your head before asking questions.

What are 3 types of chromatography?
1. thin -layer chromatography 2. gas chromatography 3. liquid chromatography
What is fish-tailing for vehicle driving safety?
Fish-tailing is were the back of the car loses traction and starts to slide side to side. If not corrected the car will spinout.
Why ethanol not suitable in Gas chromatography?
Its alcohol so it can purify the chemicals used in the experiment. Furthermore, it will travel up the filter paper better than water will. Ethanol is pure whereas water may have other things in it such as chlorine is in tap water

What is tailing effect in TLC?
Tailing effect is an error that occurs when the spot is not allowed to dry hence leading increased diameter of the spot in a TLC plate. Nwando Ata.
