CAMAG TLC Visualizer 2 - Introduction and Overview; Safety Precautions

Introduction
Instruction Manual, Oct-16 2
1 Introduction
The CAMAG Visualizer 2 has been designed specifically for digital documentation of thin-
layer chromatograms and similar flat objects.
UVA (365 / 366 nm broadband) direct light. (see appendix)
This type of illumination is used for thin-layer chromatograms and other fluorescent
objects.
Under this light fluorescent objects appear as bright and often differently coloured spots
on a dark background. The higher the density of the UV radiation and the more effectively
the visible light is filtered out and extraneous light screened off, the greater the sensitivity
of detection by this method. The fluorescence indicator F254 frequently present on thin-
layer plates is not necessary for this mode of detection, but does not interfere with it
either.
UVC (254nm narrowband) direct light. (see appendix)
This type of illumination is used almost exclusively for thin-layer chromatograms.
Substances which absorb this light appear under it as dark spots on a bright background
if the layer contains an appropriate F254 fluorescent indicator. UV density and elimination
of visible light are less critical for this mode of detection.
White light (direct or transmitted, separately and combined)
Used for recording visible, opaque objects.
For recording translucent objects such as thin-layer chromatograms, direct light alone
gives the best color accuracy, a combination of direct and transmitted light intensifies the
contrast.
Transmitted light should be used for recording transparent objects.
1.1 Precaution
• Please read this operating manual before starting the installation!
• This manual contains information and warnings the user has to follow to
ensure reliable operation of the instrument.
• Some interior parts of the instrument are under AC power. Careless and
improper use can cause injury. Unauthorized manipulations can cause
damage
• This sign indicates (on instrument and in this manual) that failure to take
note of the accompanying information may result in damage of the
instrument
• The instrument is manufactured and tested in accordance with the
respective European safety regulations (see Declaration of Conformity). The
instrument complies with safety class 1 and has been designed for indoor
