Ul tra I I® Columns
Ultra II® IBD Columns
Chromatographic Properties:
An intrinsically base-deactivated (IBD) phase, containing a polar group within, or intrinsic
to, the hydrocarbon bonded phase. Unique selectivity and high level of base deactivation,
while reducing or eliminating the need for mobile phase additives. Great for mixed polar and
nonpolar compounds.
Physical Characteristics:
particle size: 3µm or 5µm, spherical
pore size: 100Å
carbon load: 12%
endcap: no
pH range: 2.5 to 8
temperature limit: 80°C

ordering
note
We strongly recommend ordering a semi-prep
or prep column only after evaluating the desired
separation on an equivalent analytical-scale
column. Because we cannot re-use a column or
the silica it contains once it has left our facility,
we cannot accept returns of large-scale columns
(except in cases of our error).
Supersize without
surprise!
