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
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.
