Allure
®
Biphenyl HPLC
Columns Flyer
Analyses of corticosteroids,
contraceptive steroids, and
endogenous steroid hormones
show the unique separation
mechanism of theAllure
®
Biphenyl phase - pi-pi interac-
tions - providesmarkedly
better selectivity, relative to a
C18 or phenyl phase, formole-
cules that differ in the number
or positions ofmultiple bonds.
For saturated analytes the
Allure
®
Biphenyl phase has
retention and selectivity
similar to aC18 phase, but
superior to a phenyl phase.

Allure®OrganicAcidsColumns
ChromatographicProperties:
Allure®OrganicAcids columns provide enhanced retention and selectivity for polar organic acids, allowing the
separation tobe performedon a single 30cm column.AnAllure®OrganicAcids column effectively resolves key
organic acids such as tartaric andquinic acids, using the chromatographic conditions specified inAOACmethod
986.13.Retention is stable and reproducible, evenwith the 100% aqueousmobile phase specified in theAOAC
method.
