Scanner 4 for Densitometric Evaluation of Thin-Layer Chromatograms 


The TLC Scanner 4 is the most advanced workstation for densitometric evaluation of Thin-Layer Chromatograms. It can also be used for densitometric measurements of other planar objects, such as electrophoresis gels. All functions of the scanner are controlled by winCATS. Only the positioning of the object to be measured is performed manually. If desired for control/positioning of the scan start position the internal illumination can be switched on. Optimal settings of the electronic amplification are automatically selected for measurements in absorption and fluorescence mode. The 16 bit A/D converter ensures optimal adapted resolution of the measurement signal.
