EPOCOD™ is a compact and economical unit placed between an HPLC column and detector, designed to facilitate post column chemical derivatization.  The kit includes a PTFE knitted reactor coil, a column jacket for temperature control and a “T” connector for convenient mixing of the analyte with post column chemical derivatization agents.

A standard EPOCOD™ comes with a knitted reactor coil 5 meters long x 0.5 mm ID in a 4” long column jacket (EP B-4-5-50).   Other combinations of knitted reactor coils and column jackets can be provided based on your specific analytical needs.  A water circulator is used in conjunction with the column jacket to control the temperature of the post column chemical derivatization reaction. Ordering information for PolyScience brand water circulators can be found here.

Aura is also a distributor for Masterflex peristaltic pumps. These economical and compact units are a perfect solution for providing the second pump needed for post column chemical derivatization. Ordering information for Masterflex brand Peristaltic Pump Systems can be found here.
