Economical Post Column Derivatisation Kits

Aura Industries has introduced its new EPOCOD™, a compact and economical unit placed between an HPLC Column and Detector.

The EPOCOD™ is designed to facilitate post column chemical derivatisation. 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 derivatisation agents.

The Standard EPOCOD™ comes with a knitted reactor coil 5 meters long x 0.5mm 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 the users specific analytical needs. Lengths are available from 5 to 25 meters, ID’s of 0.25 and 0.5mm and column jackets of 4" and 10".

To complete the kit, Aura also provides an optional Water Circulator used in conjunction with the column jacket to control the temperature of the post column chemical derivatisation reaction and a compact peristaltic pump as an economical solution to providing the necessary second pump.

An extensive Bibliography with hundreds of applications for the use of post column chemical derivatisation including the sensitive

determination of free formaldehyde in cosmetic preservatives is available.
