Detection Enhancement for
Aflatoxins,
Phenylurea Pesticides, Barbiturates and Other
compounds
Photo chemical
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 Photo Chemical Reactor are analysis of
Aflatoxins in foods, Phenylurea Pesticides in
water and Barbiturates in biological samples.
Photo chemical 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 Photo chemical
derivatization for Aflatoxins allowing
detection at sub-ppb levels.
Photo Chemical 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.
