For HPLC applications that require enhanced compound detection sensitivity and/or selectivity, Waters provides a set of add-on components to provide single-or-dual-stage post column reaction capabilities. this is comprised of the Post Column Reaction Module (PCRM), and the Temperature Control Module (TCM II).
The PCRM is an optimized, two-stage, post-column reactor oven for online derivatization. the oven incorporates a proprietary reaction coil and patented counter-current heat exchanger to minimize bandspreading and increase sensitivity.
