Abstract: Processes and systems for providing analytical device analysis advisory information are provided. Aspects of the subject processes and systems include use of an advisory module that generates analytical device analysis advisory information based on a sample identifier and instrument parameter. Also provided are computer program products for use in executing the subject processes.

Abstract: A substrate for retaining a particulate packing medium within a chromatography column is disclosed. The substrate is formed from a polymer material and positionable to retain the packing medium within the column. The polymer has pores sized to retain the packing medium within the column but allow fluid, such as transport liquid or carrier gas to pass through. A method of forming the substrate within the column is also disclosed. The method includes placing a polymer precursor into the column and then polymerizing it to form the substrate.

Abstract: A pipetting device includes first and second bodies, through which a plurality of pipettes extend. The surface of one of the bodies is free to move relative to the surface of the other body. Relative motion between the two bodies causes an inter-pipette distance exhibited by the pipetting device to vary.

Abstract: A device for holding an elongated item includes a base member and first and second mounting brackets positioned on the base member. First and second fittings are positioned on the mounting brackets. The fittings are respectively engageable with ends of the elongated item. The second mounting bracket is movable on the base member to permit positioning of the elongated item between the fittings. A restraining mechanism is positioned between the base member and the second mounting bracket for holding the bracket in a predetermined position.

Abstract: The present invention is directed to a chromatographic separation system, separation unit, and method of use thereof. A separation unit comprises two or more regions, each region having a different cross-sectional area. The separation unit includes single column and multiple column configurations. The invention is also directed to an embodiment of a separation unit containing a solid stationary phase for chromatographic separation, the separation unit comprising two or more contiguous regions, wherein each region has a unique cross-sectional area.

Abstract: An apparatus and method for adjusting the orientation of a lubricant-retaining basin is disclosed. The apparatus includes a cabinet configured for retaining a vacuum pump and a lubricant-retaining basin. A rotatable member engages the lubricant-retaining basin and elevates the back end of the basin to permit drainage of lubricant from the front end of the basin.

Abstract: An apparatus for collecting lubricant, such as from a vacuum pump, is disclosed. In certain embodiments the apparatus includes a cabinet for retaining a vacuum pump and a variable depth basin beneath the cabinet for collecting lubricant from a vacuum pump. In specific implementations the variable depth basin is deepest proximate the front of the cabinet.

Abstract: An cabinet for retaining a vacuum pump. The cabinet includes, in certain embodiments, removable access panels that allow access to the interior of the cabinet and to a vacuum pump placed within the cabinet. In certain embodiments the cabinet includes a top surface and at least one side surface. Portions of these top and side surfaces are removable from the cabinet to allow access to a vacuum pump that can be placed within the cabinet.

Abstract: Methods of and an apparatus formed by a combination of components for automated fluid processing through use of structures integrated within plates or cartridges receivable by autosamplers, that include at least one inlet, at least one outlet, and stationary phase material disposed therebetween. An enclosed fluid processing pathway is formed by automatically connecting an autosampler fluid transport connector, such as an autosampler needle, to each of the inlet(s) and outlet(s) and simultaneously injecting a fluid to be processed into the inlet(s) and extracting processed fluid from the outlet(s).

Abstract: Devices, and methods of use thereof, receivable by autosamplers for processing fluids contains suspended solids and solubles in, for example, solid phase extraction, include an inlet chamber in fluid communication with an outlet chamber through an integral fluid pathway. One or more autosampler needle(s) may inject the fluid into the inlet chamber, which contains a separation medium through which the injected fluid flows prior to flowing into the outlet chamber, from which fluid may be withdrawn by the autosampler needle(s). A pressure tight seal may be formed between the needle(s) and inlet chamber, and backflow is preventable from the outlet chamber to the inlet chamber. Numerous embodiments of the device are described, including well plate configurations and structures graspable by autosampler robotic devices and/or which may be held in autosampler trays.
