Aura Industries Inc. introduces a series of column jackets for the effective and economical temperature control of HPLC columns ranging from the analytical through preparative and process sizes. Temperature control from -30°C to 90°C provides improved reproducibility. Use of above ambient temperatures reduces back pressure, improves resolution and increases throughput. For reverse phase chromatography, increased temperature allows a decrease of expensive organic solvents in eluent.
The column jackets are used in conjunction with circulating water baths which have high heating and/or cooling capacities. The excellent heat exchange capability of circulating liquids ensures uniform temperature of the columns without " hot spots". Use of below ambient temperature improves many chiral separations. The column jackets are constructed from unbreakable plastic and brass. Four inner diameters are available: 1 1/8, 1 3/4, 3 and 5 inches in a variety of lengths.
