PHOTOCHEMICAL DERIVATISATION

UVE Derivatisation of Aflatoxins with UV Light

The UVE photochemical reactor enables aflatoxins to be analysed with HPLC fluorescence in the simplest way.

NEW:
Improved reactor-coil available as an upgrade , for faster and more cost-effective mycotoxin analysis!

UPGRADE AVAILABLE NOW

Improved
Reactor coil for UVE

The new reactor coil for the UVE photochemical reactor ensures significantly shorter chromatographies, a 10 % increase in sample throughput, increased sensitivity and constant efficiency.

Further highlights:

  • Reduced peak width (almost 40 %)
  • Optimised LOD/LOQ, while maintaining the same chromatography parameters
  • Linear performance over the entire spectrum of analyte concentration
  • Compatible with HPLC sampler injection and our fully automated sample preparation devices

UVE ADVANTAGES AT A GLANCE

Photochemical, Simple and without Chemicals

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

Wide range of uses

Can be used for the analysis of vitamin B3 (niacin) and cosmetics (NDELA)
The UVE can also be used in the analysis of niacin (vitamin B3) and for cosmetic products for the detection of the carcinogenic compound N-nitrosodiethanolamine (NDELA) according to ISO/DIS 10130 (method K84.00-7 (EC)).
