Extended Linearity

Since visionCATS 4.0, TLC Scanner 4 and TLC Visualizer step parameters allow to specify the Profile representation mode between two options:

  • Classic (default) corresponds to the TLC Scanner profiles or spectra, or profiles generated from TLC Visualizer images, as they were generated in previous versions. Profile/spectra values are always <= 1.

  • Extended Linearity (recommended), based on the theory of reflectivity, which applies a linear relationship between the signal and the substance amount, leading to an increased linearity range. This mode only changes the way profiles are generated from R White images of the TLC Visualizer, and TLC Scanner profiles/spectra in Absorbance mode. Profile/spectra values are always <= 9.
