HPLC Column Symmetry C18 3.5µm 4.6x75mm ECD PQ

These reversed-phase columns incorporate Waters' embedded polar group technology, which "shields" the residual silanol surface of silica from highly basic analytes. The reduced silanol activity of the SymmetryShield RP18 column significantly improves peak shape and resolution.

This SymmetryShield column from Waters has a length of 75 mm and an inner diameter of 4.6 mm with a particle size of 3.5 µm.

In the development of analytical methods for pharmaceutical and biopharmaceutical products, the reproducibility of HPLC columns is of critical importance. The column-to-column and batch-to-batch reproducibility of the Symmetry family is unmatched by any other brand of silica-based HPLC columns.

Symmetry columns, available as columns and precolumns, are manufactured using high-purity silica and tightly controlled manufacturing processes, giving you a column whose performance exceeds HPLC column standards.
