Aura Industries has introduced its Epocod, a compact and economical unit that can be placed between a HPLC column and detector.
The kit includes a PTFE knitted reactor coil, a column jacket for temperature control and a T-connector for mixing of the analyte with post-column chemical derivatisation agents.
The standard Epocod comes with a knitted reactor coil 5m long x 0.5mm ID in a 4in 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 5m to 25m, IDs of 0.25mm and 0.5mm and column jackets of 4in and 10in.
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 is available that contains hundreds of applications for the use of post-column chemical derivatisation including the sensitive determination of free formaldehyde in cosmetic preservatives.
