Ultra IBD 3µm & 5µm Columns
An intrinsically base-deactivated (IBD) phase, containing a polar group within, or intrinsic to, the hydrocarbon bonded phase. Unique selectivity and a high level of base deactivation, while reducing or eliminating the need for mobile phase additives.
particle size: 3µm or 5µm, spherical
pore size: 100Å
carbon load: 12%
endcap: no
pH range: 2.5 to 7.5
temperature limit: 80°C
Specialized Columns for Mixed Polar and Nonpolar Compounds
The polar group in Ultra IBD columns assists in deactivating surface silanols and participates in providing unique separation selectivities for acids, bases, zwitterions, and other polar compounds.
