A detection reagent is disclosed in the form of a dye having the basic structure of a 4-(phenylethynyl)-phenyl-amine, a 4-(phenylethenyl)-phenyl-amine and/or a biphenylamine derivative. The dye can be used as detection reagent for nitroaromatics, nitroalkanes, nitroamines, nitrates, nitric acid, nitrous acid, nitrogen oxides, and additionally for sulphur dioxide (which is produced with the degradation of black powder). The dye can be an asymmetric triphenylamine derivative, which can lead to a fluorescence quenching, which can be used analytically in the case of electron abstraction.

The invention is directed to a method and a kit for calibrating a photoluminescence measurement system, in particular a fluorescence measurement system. The kit includes a number of fluorescence standards i and their corrected and certified fluorescence spectra I(&#x3bb;), whereby the fluorescence standards i are selected, so that their spectrally corrected fluorescence spectra I(&#x3bb;) cover a broad spectral range with high intensity. The standards are characterized by large half-widths FWHMof their bands of at least 1400 cm. According to the method of the invention, partial correction functions F(&#x3bb;) are generated by forming the quotient of the measured fluorescence spectra J(&#x3bb;) and the corresponding corrected fluorescence spectra I(&#x3bb;), which are then combined to form a total correction function F(&#x3bb;) for a broad spectral range. The combination factors &#x3b1;are hereby computed by statistical averaging of consecutive partial correction functions F(&#x3bb;) over only a predefined, limited overlap region &#x3bb;&#xb1;&#x394;&#x3bb;about the mutual crossover wavelength &#x3bb;.
