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 |
20100156089 | End fitting for high pressure capillary tube - The fitting includes an elongated cylindrical body with a conical ferrule secured to its forward end, and with the body and ferrule having aligned through bores sized to allow a capillary tube to be passed through them. The elongated body has medially located external helical threads, and a knurled nut is rotatably coupled to these threads. The body also has elongated axially directed gripping fingers with inwardly facing gripping regions thereon normally spaced from but suited to be biased radially against the capillary tube in the fitting bores. A tubular gripping nut is threaded onto the external body threads, suited to be axially shifted along the body upon relative nut/body rotation. The nut and body have cooperating cam surfaces suited to engage upon relative nut/body rotation and bias the finger gripping regions tightly against the capillary tube for securely retaining tube as positioned within the fitting. | 06-24-2010 |
20100258487 | HPLC schematic with integrated sample cleaning system - The disclosed HPLC flow schematic back-flushes the guard column with mobile phase once every operating cycle, the regular cleaning maintaining its effectiveness and useful life. This mobile phase flow reversal is accomplished by imposing a two position multiple port switching valve between the guard and separation columns. In one valve position, the mobile phase is pumped in one flow direction through both the separation and guard columns, but the switched valve maintains the same flow direction only through the separation column and reverses the mobile phase flow direction through the guard column, for effectively cleaning the guard column. Moreover, the mobile phase back flow is directed over the emptied sample drawing needle for cleaning it to reduce possible sample cross contamination. The improved flow circuits use basically only the typical HPLC system components, except for some insignificant modifications from existing injector designs. | 10-14-2010 |
20110025047 | End fitting for holding a high pressure capillary tube - The disclosed fitting has a tubular body externally threaded at one end, to allow the fitting to be positioned over a capillary tube and connected to a cooperating component. The fitting has opposed gripping jaws at its other end suited for being flexed against the capillary tube for holding it relative to the fitting. A tubular nut fits over the gripping jaws, and cam faces provided between the nut and jaws serve to tighten or release the jaws relative to the tube, depending on which direction the nut is shifted axially along the body. The outside tubular face of the actuating member is knurled, providing for reliable manual gripping and axial shifting the actuating member. | 02-03-2011 |
