Green Flash Chromatography
Efficient & fast sample elution by Yamazen’s automatic method setting, based on true theory of chromatography, Rf Gradient
Inappropriate Gradient results in inefficient & lengthy chromatography on systems from other companies
Resulting chromatograms are
TLC
Rf=0.07
10%EA/Hex
Rf gradient is applied per Yamazen’s automatic setting
4 CV240ml solvent
Target always elutes at around 4 column volume area resulting in ideal separation.
Other companies’ TLC gradient
11 CV660ml solvent
Broad peaks and poor separation
Flash systems of other companies are not based on the true theory of theflash chromatography; run time and solvents are substantially wasted, which result in poor purification.

●Green Flash Chromatography is the ultimate flash chromatographic technology that achieves most efficient sample purification.●The sample run is always carried out with minimum eluting volume. It minimizes run time and solvent use while achieving a good separation. It is Eco-friendly!●Optimum method will be developed automatically based on the true theory of the flash chromatography, with the simple input of the TLC results, which allows easy sample purification.
