Kromasil CelluCoat

analysis

You are working with HPLC for the separation and identification of analytical substances in laboratories. Challenge the selectivity of Kromasil for your most sensitive analysis.

development

You need to quickly purify substances for further studies in the development of pharmaceuticals. Kromasil will help you achieve your goals with ease and efficiency.

production

You are using preparative chromatography for high efficiency purification in a pilot or up to industrial-scale production. The robustness of Kromasil is available in ton quantities to meet your process demands.

Stable performance

Switching between compatible organic mobile phases will not lead to any degradation in performance

Performance after mobile phase changes

“Make every day's work easier”

You can run Kromasil CelluCoat with maintained stability and performance when switching between compatible normal or polar organic phases. Figure 1 illustrates the impact of a mobile phase switch from heptane/2-propanol (90/10) to 100% acetonitrile and back, then to 100% 2-propanol and back. Performance is measured with trans-stilbene oxide as the efficiency on the first eluted peak (Knox plot) and the selectivity. Neither seems hardly affected by the mobile phase switches.
