UVE™ Photochemical Reactor

Photochemical derivatization is a simple, inexpensive and flexible technique that improves sensitivity and selectivity of detection for a broad range of analytes in HPLC.  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.

The photochemical reactor has a 254 nm lamp and a knitted reactor coil.  Key Features are:

  • 254 nm UV low pressure lamp with cooled reflector tube
  • Long term stability of lamp and coil
  • High light transmission
  • Robust steel housing to meet laboratory requirements
  • Special designed fluorocarbon coil
  • Photochemical post-column derivatization of Aflatoxins in a special reactor loop with UV light
  • Result: clear peaks
  • Comparable to electrochemical derivatization with Cobra Cell
  • AOAC accepted methodology
  • Standard reactor volume: 1.0 mL
  • Easy installation and no special reagents as used in derivatization
