Functional Group Reactive Labels for Chromatography

General Features & Benefits

Measured light parameters are positive (light signal is zero in absence of fluorophore)
Fluorophoric species relatively rare in analytical matrices, low background noise levels are obtained
Detection problems caused by lack of universal detectors for HPLC can be solved partially, by UV and fluorescence derivatization techniques
High sensitivity
Pre-column derivatization offers simplicity and less reagent demand as compared with post-column derivatization

Column Chromatography

Pre- and post-column derivatization techniques
Reversed-phase chromatography (including ion pair chromatography) frequently applied
Ion exchange chromatography (IEC) systems

Thin layer Chromatography
Pre- and post-separation derivatization techniques
