The
columns quickly separate the mycotoxins Aflatoxin G2, G1, B2, and B1,
which are known as liver carcinogenic substances. Especially with UltraSep ES
TOX1 the chromatogram is not interfered with eluent peaks. UltraSep ES TOX2 is
based on a wide-pore gel for quick analysis.
To
get a low determination limit of 0.5 ppb, fluorescence detection is used. For
this, a post-column derivatization by bromination with pyridinium tribromide (pyridinium
bromide perbromide) is necessary.
Best,
one works with a CoBrA-Cell (Coring System Diagnostik GmbH, Gernsheim), in
which the bromine is generated from KBr electrically.
