TLC Visualizer 2
The visual presentation of the complete chromatogram showing all samples and standards side by side is one of the most convincing arguments for (High-Performance) Thin-Layer Chromatography. No other chromatographic technique can directly express the result as a color image and make it available for visual evaluation.
To reproducibly acquire and preserve best quality images of TLC/HPTLC chromatograms under different illuminations this high-end imaging and documentation system is available. With its digital CCD camera a maximum resolution of 82 μm on the plate is obtained.
For electronic image acquisition the camera – like the human eye – captures polychromatic visible light. Under white light illumination it is the light reflected from the layer background. Under long-wavelength UV light (366 nm) it is the light emitted by fluorescent substances. When short-wavelength UV light (254 nm) is used, substances absorbing UV 254 appear as dark zones, provided the layer contains a fluorescence indicator (fluorescence quenching).
Key Features:
- CCD camera
- Illumination under UV 254 nm, UV 366 nm, and white light
- Side by side comparison of tracks with Comparison Viewer
- Image-based evaluation
- Any plate format up to 20 x 20 cm
- Software-controlled with visionCATS
