Inertsil ODS-4 HPLC Columns
Excellent peak shapes for both strong acidic and basic compounds
Our newly-developed endcapping technique ideally
deactivates the silanol groups, suppressing the adsorption
of common basic compounds as well as strong ones,
which leads to sharper peaks.
Moreover, the new endcapping technique prevents the
adsorption of strong acidic compounds as a surface of the
packing material becomes neutral.
Excellent analysis stability
of strong metal chelating
compounds
In order to stably analyze strong metal chelating
compounds, samples were injected repeatedly before
the analysis to mask the adsorption active sites on the
surface of the packing material or addition of EDTA to
the eluent were required. Column equilibration was also
time-consuming. Since the trace amount of metals has
been eliminated from the surface of the packing
material, it allows a stable analysis from the 1st injection
requiring no masking process.
Excellent analysis stability
under 100% aqueous eluents
Inertsil ODS-4 minimizes the dewetting phenomenon
while maintaining the same retention characteristics to
that of common ODS columns. Therefore, Inertsil ODS-4
can be used at ease under 100% aqueous eluents.
Furthermore, the packing material that achieves a stable
analysis using 100% aqueous eluents provides another
advantage: which reduces the column equilibration time
returning to an initial eluent condition in gradient.
