A method for producing lead-212 of very high radiological purity from an aqueous solution comprising thorium-228 and daughters thereof. Manufacture of radiopharmaceuticals based on lead-212, which are useful in nuclear medicine and, in particular, in targeted alpha radiation therapy for the treatment of cancers.

An apparatus for collecting mineral particles in a slurry or the tailings is disclosed, including a collection area or tank having one or more collection surfaces configured to contact with a mixture having water and valuable material, the valuable material having a plurality of mineral particles of interest; and a synthetic material provided at least on the one or more collection surfaces, the synthetic material having plurality of molecules with a siloxane functional group configured to attract the mineral particles of interest to the collection surfaces. The one or more collection surfaces includes a conveyor belt that is driven through the collection area or tank, through a release area or tank, back through the collection area or tank. The mixture includes a pulp slurry having ground ore with mineral particles of interest forming part thereof, including mineral particles of interest of about 500 microns or larger.

The present invention provides a column filler for liquid chromatography that has a great adsorption capacity, adjustable adsorption selectivity, and high shape retainability and therefore is usable for measurement of various substances and capable of achieving excellent separation performance and a high filling rate in a column when used as a column filler for liquid chromatography. Provided is a column filler for liquid chromatography including carbon-coated porous particles, the carbon-coated porous particles including porous particles each having a coating layer containing an amorphous carbon on a surface.

A system is provided for removing arsenic from water to safe levels at or below the EPA standards. The system is a hybrid spouted vessel/fixed bed filter system that significantly enhances/improves arsenic removal for drinking water using zero-valent iron (ZVI) particles. Movement of the circulating, iron-containing particles in a dense moving bed that forms on the spouted vessel bottom creates an abrasive “self-polishing” action among them that continuously generates colloidal iron corrosion products. This material then circulates with the water in the vessel and is removed and concentrated in a fixed bed filter. The colloidal material captured and immobilized in the filter has been shown to remove arsenic from contaminated water at very rapid rates.

A blood treatment system comprising at least one first device and at least one second device, wherein the first device is a membrane filter for the removal of toxic mediators from blood and the second device is suitable for the removal of granulocytes and monocytes from blood. The first device has a first blood flow path a first blood flow path for conducting blood through and the second device has a second blood flow path. The first and second devices are serially connected in succession in such a way that the first blood flow path is in fluid communication with the second blood flow path.

The membrane has an interior filter space in its housing and a semipermeable membrane arranged in the interior filter space, which membrane divides the interior filter space into a retentate chamber and permeate chamber. The housing has a blood inlet device and a blood outlet device that are in fluid communication with the retentate chamber, as well as a permeate outlet for diverting permeate from the permeate chamber. The blood inlet device, the retentate chamber and the blood outlet device form the first blood flow path. The membrane filter has a separation characteristic such that the sieve coefficient for albumin, SK.sub.Alb, is within the range from 0.015 to 0.35.

A sample injector configured to introduce a sample fluid into a mobile phase, wherein the mobile phase is to be driven by a mobile phase drive through a separation unit for separating compounds of the sample fluid in the mobile phase, wherein the sample injector comprises a metering device being operable for displacing fluid and for intaking a metered amount of the sample fluid into the sample injector, an injector valve being switchable for operating the sample injector selectively in a sample intake mode in which the metering device is operable to intake the sample fluid from a sample container, or a separation mode in which intaken sample fluid is driven between the mobile phase drive and the separation unit for separating the compounds, and a flow direction controller configured for defining an enabled flow direction of fluid displaced by the metering device and for defining a disabled flow direction.

A system for separating and concentrating a component of a whole material is disclosed. The whole material can include a material that has more than one component, such as whole blood that can include at least red blood cells, monocytes, and plasma. The system can include a substantially single container including a separation section and a concentration section wherein a component can be moved from the separation section, after a separation, to the concentration section to be concentrated. The concentrated component can then be withdrawn from the separation and concentration container for a selected procedure.
