High performance thin layer chromatography (HPTLC) is an enhanced form of thin layer chromatography (TLC). A number of enhancements can be made to the basic method of thin layer chromatography to automate the different steps, to increase the resolution achieved and to allow more accurate quantitative measurements.
Automation is useful to overcome the uncertainty in droplet size and position when the sample is applied to the TLC plate by hand.
