Abstract: A femoral reamer (100) can include a base material (304) and a coating (302) disposed on the base material. The coating can be harder than the base material and, as a result, the femoral reamer can wear more slowly than if the coating was absent. The coating can be a different color than the base material. When the coating is worn off, such wear can be easily observed from a visual inspection of the femoral reamer. The coating can have an initial thickness (i.e., a thickness prior to use) that is related to a tolerance on a size and/or a shape of a hole drilled by the femoral reamer. When the coating is worn off, the size and/or the shape of the hole drilled by the femoral reamer may be at or near an edge of a specified tolerance range. The femoral reamer can be part of a kit and a method.

Abstract: A device (20) used during a medical procedure to engage a cross-section of a bone is disclosed herein. The device is selectively expandable to correspond to the cross-section of the bone. Once the device is properly sized, the device is used as a sizing tool to select the proper size of an implant or as a surgical guide for preparing the bone with a surgical instrument, for example.

Abstract: The present invention is directed to a system for converting between single flow and split flow evaporative light scattering detection devices for detecting samples in a mobile phase. Included in the system is a evaporative light scattering detection device, a low temperature adaptor, and a connection tube for providing a fluid connection between the evaporative light scattering detection device and the low temperature adaptor.

Abstract: Methods and devices for continuous electrochemically suppressed ion chromatography are disclosed. In preferred aspect of the invention, a chromatography effluent comprising analyte ions and electrolyte is split into a first chromatography effluent flow stream and a second chromatography effluent flow stream. Electrolysis ions selected from the group consisting of hydronium ions and hydroxide ions are generated by the electrolysis of water. Electrolysis ions of the same charge as the electrolyte and the second chromatography effluent stream are flowed through a stationary phase thereby suppressing the electrolyte in the second chromatography effluent flow stream. The analyte ions are subsequently detected in the suppressed second chromatography effluent flow stream.

Abstract: Methods and devices for removing gas prior to detecting analyte ions are discolored. In one aspect of the invention, gas by-products from the suppression of the mobile phase are removed prior to detecting analyte ions at a detector. In another aspect, the amount of dissolved carbonic acid is reduced in a suppressed carbonate/bicarbonate mobile phase by removing carbon dioxide gas.
