The applications

Development or derivatization is a crucial step in TLC In addition to the Retention factor (distance travelled by the spot in relation to that travelled by the eluent) it enables the identification of a component to be confirmed by chemical reaction.

In comparison to the conventional method of pulverisation, the reagents described need to be adapted for use with Derivapress®. Consequently, in order to respect the chemical reaction conditions, the reagent must be diluted to between 1/5 and 1/10 concentration depending on the individual case. It may also be necessary to add ethanol to improve diffusion of the reagent in the Derivamouss®.

The applications illustrated will give you some examples of the methods and reagents used.
