ved hjælp af en kontrolprøve under tilstedeværelse af borsyre kan en evt. falsk fluorescens bestemmes (ved dannelse af et kompleks af borsyre og dehydroascorbinsyre) og fratrækkes den fluorimetriske bestemmelse.
a control test in the presence of boric acid enables spurious fluorescence to be determined (by the formation of a boric acid/dehydroascorbic acid complex) and the fluorimetric determination to be deduced.
