Relative Retention in TLC r_ij Using Column Liquid Chromatography Terms

Abstract

Using new approaches for conversion of TLC retention data in terms of column liquid chromatography (CLC), a new term of relative retention r _ij for TLC is proposed:

The new relative retention term r _ij can be used in TLC as a chromatographic constant. It was shown that r _ij ≠R _fi /R _fj . Different meanings of retention terms in CLC and TLC mode are compared.

Keywords:

• TLC
• Relative retention
• Relative retention in TLC
• Comparison TLC and CLC
