Automatic sample application is a key factor for productivity of the HPTLC laboratory. The ATS 4 offers fully automatic sample application for qualitative and quantitative analyses as well as for preparative separations. It is suited for routine use and high sample throughput.

The Derivatizer is used for automated reagent transfer in the derivatization of thin-layer chromatograms and sets a new standard of reproducibility by employing a unique “micro droplet” spraying technology (patented). The Derivatizer ensures homogeneity and convenience in applying derivatization reagents, and offers other advantages as compared to manual spraying and immersion. The device is suitable for all common reagents. To meet the divergent physicochemical properties of the reagents, e.g. viscosity, four different color-coded nozzles are available, and the user can select from six spraying modes.
