Torus Diol (OH) Column, 130Å, 1.7 µm, 3 mm X 150 mm, 1/pk

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.

A set of columns with considerably different selectivities and high retentivity is essential for method development. In order to offer a wide range of selectivities for acids, bases, and neutral analytes, the Torus Chemistries were specifically chosen. To give users more selectivity options, Torus DIOL Columns were created. When combined with additives, high-density diol surface bonding increases the durability of the overall approach and provides chromatographic performance comparable to that of conventional, unbonded silica phases

The Torus phases are based on a new, patent-pending two-stage functionalization of the ethylene bridging hybrid (BEH) particles. Modification of the stationary-phase surface during traditional SFC separations has been shown as the primary source of chromatographic variance. The ACQUITY UPC2 Torus series of columns addresses this issue using a two-stage bonding process that protects the stationary-phase surface from these undesired reactions and results in columns with excellent chromatographic performance.

The initial bonding creates a hydrophilic surface that regulates the sorbent's retention properties and is in charge of reducing undesired surface interactions that eventually cause changes in selectivity and retention. Each Torus chemistry's unique selectivity and peak shape properties are a result of the second functionalization process. These procedures provide a number of stationary phases with wide selectivities that retain reliable chromatographic performance for the duration of the column's life.
