A new photochemical reactor design for the treatment of .

In this work, the technical design concept for mixing in a cylindrical reactor has been approached in a rational way for the treatment of compounds in highly absorbing solutions. The new photochemical reactor perfected in our laboratory consists of an annular reactor with one UV lamp in axial position.

Crocheted PTFE reactors for post-column photochemistry in .

Construction of crocheted photochemical reactors for use in high performance liquid chromatography is described. The design of these reactors is optimal for low intensity light sources because of their cylindrical configuration. Band broadening is minimized by the use of tightly crocheted narrow bore tubing and fittings modified to reduce dead volume.
