Introduction
Instruction Manual, Oct-16 2
1Introduction
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.

2.6 Settings in visionCATS
Reference point
Under Options/General Setting/ Global Configuration the setting „TLC Visualizer 2
uses the same reference point as a TLC Scanner 3/4” is active by default. This sets
the reference point as on the TLC Scanner, ATS 4 and Linomat 5. If active, the
plate has to be inserted with the application position first. If the instrument is used
to check the plate through the viewing flap or if the reference point has to be
identical as in first generation CAMAG TLC Visualizer, this option has to be
disabled in visionCATS. The plate has to be inserted with the solvent front first
To change the reference point:
•Go to Options/General Setting/ Global Configuration
•Under Analysis deactivate the point “TLC Visualizer 2 uses the same
reference point as a TLC Scanner 3/4”
•Save the setting
Set the lens focal length
•Double click the TLC Visualizer in the “Instruments” window
•In the “Properties” sub-tab, under “Lens” choose the correct focal length
for the lens of this specific CAMAG TLC Visualizer
•Save the setting
If this setting was changed (by accident or the lens had to be changed), the
Diagnostics session needs to be re-done.
Electronic adjustment
To record images with the correct settings (white adjustment and position), the
Diagnostics session has to be performed.
•Double click on the instrument icon in the “Instruments” window
•Chose the subtab “Diagnostics”
•Press “Start” and follow the instructions
To display images with the correct colour, you will need a calibrated PC screen
To print images (on reports or exported) with the highest possible consistency
between screen and printed image, the printer has to be calibrated. Printed images
appear different as the printer parameters (resolution and colour depth) are
different to those of the PC screen.

Getting started
Instruction Manual, Oct-16 9
As colours are always seen subjectively, slight differences in perception of the plate
seen through the viewing flap, the recorded image on screen and the printed
image are possible.
