nSample application is the most critical step in the
TLC procedure.
Errors which occur during sample application,
cannot be compensated for in chromatogram
development or evaluation.

TLC Visualizer
nDesign has been enhanced to further improve the
homogeneity of the illumination of the plate:
•254 nm, short wave UV- Reflectance
•366 nm, long wave UV - Reflectance
•White light - Reflectance and/or
Transmission.
nErgonomic design: Easy access in to the illumination
compartment via large sliding door.
nseparate viewing window with UV-protection
nTimer for automatic switch-off of the light sources
Automatically finding the brightest spot (UV 366 mn)
Automatic Optimization
Manual Optimization
If desired, a region of interest can be defined, in which the brightest spot is
automatically found.
Image enhancement: exposure “normalization”
Comparing chromatography from 3
different plates
Image enhancement: “Clarify”

Pixels
R: 223;
G: 160;
B: 003;
For each R
F value the mean luminance
of the pixels (red, green, blue) in the
zone is calculated
Y = 0.3 R + 0.59 G + 0.11 B
Calculated on an aliquot of
the track (50 %)
