The New Edge in Chromatography
The Diazem bonding matrix uses well-defined processes to specifically control coverage density, silanol capture, and phase polarity. Each process can be duplicated for any main phase, particle size, pore size, and surface area.
Diazem bonded phases add power to HPLC problem solving and method development due to an enhanced ability to alter peak elution patterns (selectivity) while maintaining the same main phase. This is done by controlling the hydrophobicity as well as the surface activity of the phase toward acidic and basic moieties in the analytes. The δ-value is a quantitative measure of the selectivity of Diazem phases.
In addition to the advanced bonding chemistry used, Diazem also guarantees the highest level of column performance for all product lines.
Diazem HPLC Columns are:
► RobustBonding and column packing technology work together to produce columns with longer life.
► ReproducibleStoichiometric bonding and rigid quality control assure reproducibility.
► Well End-cappedExhaustive end-capping ensures good peak shape on acids and bases as well as neutral analytes.
► EfficientWell bonded superior native silica, which is well packed, ensures efficient columns.
