Comparison of the TLC Scanner With Video Evaluation

Comparison of determinations using a video system and a TLC scanner 

Comparative measurements have also been made on a phytopharmaceutical product. In the investigation of ginseng roots and of the medicaments prepared from this, the ginsenoside Rgi was determined by both 1-dimensional and 2-dimensional development. The results were presented in a poster in Vienna in September 1998 [124b]. 

In its house journal (CBS), CAMAG has pubhshed many comparisons between densitometric and video evaluation [124c], and has given a clear account of the current scope and limitations of the two systems  

The comparisons of the various methods of evaluation made in this Chapter are valid up to mid-1999, but the very rapid developments in the multimedia market will lead to further improvements in the future. A summarized comparison of quantitative evaluation methods for TLC up to the present time can be found in [124d].
