20100089811 | HPLC preparative column design - The preparative column has an inner thin wall HPLC compatible material tube, packed with absorbent particles, with filters and end fittings of HPLC compatible material at the tube ends. An aluminum outer sleeve tightly overlies and reinforces the inner tube, aluminum end caps overlie the end fittings and are secured to the outer sleeve. End connections in the end fittings allow solvent and sample flow through the packed absorbent. Exterior axial flats on the aluminum sleeve and end caps provide broad contact against flat thermal surfaces of conventional temperature controllers, thereby yielding effective thermal transfer there between. The flats further minimize column rolling on flat level surfaces and provide favorable locations for connection taps for conveying coolant flow through passages formed in the sleeve. | 04-15-2010 |
