Capture TLC image and show it on monitor screen
The Smart Flash AKROS integrated with TLC reader is an indispensable tool to be used by synthetic organic and natural products chemists to quickly and efficiently purify samples ranging from a few milligrams to dozens of grams. “AKROS mode” is designed based on Yamazen’s proprietary EPC (Elution Position Control) theory which is an advancement of the familiar theory of column chromatography. It calculates the sample’s elution position and the maximum sample loading amount for each column selected and coupled with a highly sensitive UV detector, elutes the target compound always at the most efficient position, assuring a high resolution in sample purification. AKROS captures a TLC image and shows it on the display screen along with the chromatograph’s sample peaks, which enables the cross-referencing of sample spots on TLC to sample peaks. AKROS, the “TLC Flash Chromatography System” helps the chemist to identify the target peak by cross-referencing TLC pattern to sample peaks and by comparing the intensity of sample peaks to the darkness or lightness of TLC spots. Moreover, it makes the result file of a sample run more useful as method data since the TLC image is copied and attached to the file.
■Cross-referencing of TLC pattern to column chromatography during run
(Target is indicated by a yellow arrow)
Elution position of the target compound is easily known by comparing the sample peaks in flash chromatography with sample spots on TLC shown on the real time monitor.
■Cross-referencing of sample spots on TLC to sample peaks in flash chromatography is also available in the result file of a sample run.
Cross-referencing of TLC to the result of sample run in flash chromatography gives important information in the result file.
Presentation on a sample run by flash chromatography can be done at a briefing session or a seminar relating it to TLC.
■Cross-referencing of sample spots on TLC to sample peaks in flash chromatography is also available in the result file of a sample run.
Flash chromatography requires a correct method transfer from TLC.
Yamazen is one and only company that can develop an optimized gradient method that predicts the elution position of the target compound upon method setting before the run.
Click on the target and the nearest impurity on TLC image captured by AKROS, and each Rf value calculated will show on the monitor screen.
Optimized method will be developed automatically when TLC solvent mixture ratio, elution mode, purification mode and a column are selected. Maximum sample loading amount for each column selected will show in the dialogue box.
Place an Inject column loaded with a sample on column stand upon completion of column equilibration, and a sample run can start immediately. A sample run can be carried out simultaneously, while checking the TLC image shown on the monitor screen.
Powerful features and functions have become available for customers due to the Yamazen’s core flash chromatography technologies.
Yamazen’s proprietary Rf gradient fully controls and determine the elution position of the target compound.
EPC (Elution Position Control) equation calculates, controls and determine the elution position of the target compound.
A slow gradient named α mode can well separate those samples whose selectivity changes much when solvent strength changes and when TLC pattern can be hardly reproduced as sample peaks in flash chromatography.
A peak width corresponding to the sample loading amount is calculated.
Maximum sample loading amount for a column selected will show on the display monitor.
Yamazen’s highly sensitive UV detector will not miss any sample spot on TLC.
Even very small spots and/or low UV spots will be well detected and separated, and TLC pattern and sample peaks in column chromatography will be accurately cross-referenced.
