smartALERT
The «classical» way of developing a chromatogram in TLC and HPTLC is to place the plate in a chamber containing developing solvent. Driven by capillary action the developing solvent moves up the layer until the desired developing distance is reached. With the aid of a stop watch or a timer the chromatographer estimates when the development process is about to finish.
But this may happen: Focusing on other work while the TLC development is in progress, the lab technician forgets to look at the watch. As a result chromatography is stopped too late; the solvent moved up too far, the analysis is ruined and needs to be repeated.
With smartALERT the chromatographer does not 'forget' the TLC plate in the developing chamber anymore. Most convenient!
