Photochemical Reactors

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.

Photochemical reactor has a 254 nm low pressure mercury lamp and a knitted reactor coil. The reactor coils are made of 0.062" OD x 0.020" ID FEP tubing. FEP polymer has UV transparency of =90% allowing for a small volume reactor thereby reducing band spreading and back pressure. Standard reactor volume is 0.75 mL.  Other volumes and 366 nm UV lamp available upon request.
