Avantor® ACE® UltraCore SuperPhenylHexyl solid-core (core-shell) particle columns are ideal for demanding MS work offering improved MS signal intensity and maximum MS response. These stainless steel columns combine high efficiency separations with low column back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and effectively eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability.

Concanavalin A is a pure Canavalia ensiformis lectin, FITC conjugated proteins or glycoproteins of non-immune origin that agglutinate cells and precipitate complex carbohydrates. They are capable of binding glycoproteins even in presence of various detergents.

Supplier: HICHROM

HALO® HPLC and UHPLC columns are based on innovative fused-core particle technology. These particles are formed from a solid core and porous outer shell. HALO® 2,7 µm columns provide the efficiency and separation speed of sub 2 µm particles but at approximately half the back pressure for the same column length. This lower pressure means that HALO® columns can be used with conventional HPLC and LC-MS systems, as well as with UHPLC systems.

Supplier: Thermo Fisher Scientific
