Long-wave UV light 366 nm
Under long-wave UV light substances that can be excited to fluoresce appear as bright spots, often differently colored, on a dark background. The sensitivity of this detection method increases with the intensity of the UV light and also as more visible light is eliminated.
Short-wave UV light 254 nm
Under 254 nm UV substances absorbing at that wavelength become visible, provided the chromatogramm layer contains a fluorescent indicator, e.g. F254. These substances appear as dark spots on a bright background (fluorescence quenching).
For inspecting thin-layer chromatograms in absence of ambient light and for safe handling the use of the CAMAG® UV Cabinet 4 is recommended.
- Two UV tubes for illumination (UV 254 nm & UV 366 nm, each 8W)
- One button operation for each UV tube
- Homogeneous illumination
- Improved user safety through tilt sensor and timer (automatic switch-off after 10 min)
