KOBRA® CELL
Art. No.: RBRK01
Product info
Intended use
Electrochemical cell for the derivatisation of aflatoxins B1 and G1 using HPLC.
General Information
The KOBRA® CELL is based on an electrochemical cell, fitted between the HPLC column, the detector which consists of a platinum working electrode and a stainless steel auxiliary electrode, separated by an ion exchange membrane. The principle of the technique is to deliver to the KOBRA® CELL, the mobile phase containing the derivatisation agent precursor, a potassium bromide salt, and aflatoxins. Bromine is then generated electrochemically by applying a constant potential at the working electrode. The resulting electrochemical reaction enables aflatoxins B1 and G1 to be derivatised in-situ to their brominated derivatives, which gives an enhanced fluorescence response.
A KOBRA® CELL measures 10 x 10 x 5 cm.
Your new KOBRA® CELL is covered by warranty for 12 months against engineering or electrical manufacturing faults from the date of purchase and when purchased through an authorised supplier. The warranty does not cover routine membrane exchanges, wear and tear damage or inappropriate use of the unit in contravention of recommended manufacturer‘s instructions.
