To produce quick, reliable achiral separations, Torus Columns are specially made to take full advantage of the ACQUITY UPC2 System's capabilities. Torus Columns' four brand-new, cutting-edge 1.7 µm chemistries for convergence chromatography streamline the technique development procedure. Excellent peak shape in these columns eliminates or reduces the requirement for additives, and they also provide increased selectivity for a variety of chemicals and greater robustness.
The construction of a method requires a set of columns with vastly diverse selectivities and great retentivity. The Torus Chemistries were carefully chosen to provide a wide variety of selectivities for acids, bases, and neutral analytes. Torus DIOL Columns were developed to provide consumers with greater selectivity possibilities. High-density diol surface bonding improves the whole approach's durability when paired with additives and offers chromatographic performance that is on par with that of traditional, unbonded silica phases.
The ethylene bridging hybrid (BEH) particles are functionalized in two stages using a novel process that is still under patent protection. The main cause of chromatographic variance has been identified as a modification of the stationary-phase surface during conventional SFC separations. This problem is addressed by the ACQUITY UPC2 Torus line of columns, which utilizes a two-stage bonding method to produce columns with high chromatographic performance while shielding the stationary-phase surface from these undesirable interactions. Initial bonding produces a hydrophilic surface that controls the sorbent's retention capabilities and is in charge of minimizing unwanted surface interactions that ultimately lead to changes in selectivity and retention. The second functionalization step is responsible for the distinct selectivity and peak shape attributes of each Torus chemistry. Several stationary phases with broad selectivities that maintain dependable chromatographic performance for the whole column life are made available by these approaches.
