PHOTOCHEMICAL REACTOR

Detection Enhancement for Aflatoxins, Phenylurea Pesticides, Barbiturates and Other Compounds.

Photochemical derivatization is a simple, inexpensive and flexible technique that improves sensitivity and selectivity of detection for a broad range of analytes. Among the applications for the photochemical reactor are analysis of Aflatoxins in foods, Phenylurea Pesticides in water and Barbiturates in biological samples. Photochemical derivatization also allows identification of closely related compounds such as polyphenols.

Pickering Laboratories Multi-residue Mycotoxins method for DON, Aflatoxins, Fumonisins, Ochratoxin A and Zearalenone
employs photochemical derivatization for Aflatoxins allowing detection at sub-ppb levels.

The photochemical reactor has a 254 nm lamp and a knitted reactor coil.

UV DERIVATIZATION RESULTS IN CLEAR PEAKS FOR AFLATOXINS

Note the short run time: B1 elutes at 9.5 Min

uve1

Without UVE™: Low response for G1 and B1

 

uve2

With UVE™: High response and no band spreading

 


Easy Handling: Simply place the UVE™
between your HPLC device and detector,
switch it on – ready to use!

 

What actually happens?
Aflatoxins B1 and G1 are transformed to stable
fluorescent derivatives resulting in clear peaks
