The low inherent fluorescence of aflatoxins B1 and G1 makes derivatisation necessary for fluorescence analysis in order to comply with analytical limit values. This can be carried out easily, conveniently and inexpensively with the UVE using photochemical radiation with UV light at 254 nm, which leads to stable, measurable fluorescence. No additional reagents need to be added.
An AOAC-recognised procedure (Waltking et al. 2006), which is an inexpensive, simple, yet stable, method of analysing aflatoxins in the ppt range, particularly for the most strictly regulated aflatoxins.
- No halogenated waste
- No special derivatisation controls necessary
- Fewer expensive chemicals
- Simple, robust use
- Long service life
