Consistent, predictable separations, column after column, time after time. When developing a new method, one of the most important goals for the chromatographer is to achieve a consistent, reproducible separation. The selection of a highly reproducible HPLC column is essential if this goal is to be attained. Syncronis™ columns achieve this goal, starting from the highly pure, high surface area silica and dense bonding, all controlled and characterized through the use of rigorous testing. New, enhanced, automated column packing methods drive consistency even further and every column is individually tested to ensure that it meets the required specifications. These extensive testing and quality control procedures ensure the delivery of a consistent product, column after column. Syncronis columns are available with 5 µm particle size for conventional HPLC applications and with 1.7 µm particle size for high speed, high efficiency UHPLC separations.
