Thin-layer chromatogram development with a moving pipette delivering the mobile phase onto the surface of the adsorbent layer.

The new approach to the development of thin-layer chromatograms is presented. For the first time we show flexible mobile phase dosage onto the surface of the adsorbent layer by moving pipette combined with precise syringe pumps. The pipette is driven into movement by computer controlled 3D machine (modified 3D printer mechanism).
