Welch Materials Boltimate EXT-C18 Columns

As a versatile C18 column, Boltimate EXT-C18 features an organic-inorganic hybrid porous layer, significantly enhancing the pH tolerance of the silica.

A Boltimate core-shell column is constructed with a 1.7 μm solid core and a 0.5 μm porous layer. This core-shell particle design delivers high column efficiency (~200,000 plates/m) and exceptional separation performance, comparable to sub-2 μm particles, while generating only 50% of the backpressure of sub-2 μm columns. The combination of high efficiency and low backpressure makes it easily compatible with existing LC systems. By simply optimizing the flow paths and detector flow cell of your instrument, the core-shell column can achieve outstanding performance under your current experimental conditions without the need for costly equipment upgrades.
