A filter element for reducing siloxane levels in a gas includes a first adsorbent material, the first adsorbent material comprising an acid-washed adsorbent; and a second adsorbent material, the second adsorbent material comprising an acid-impregnated adsorbent.

Methods, sorbent cartridges and cleaning devices are disclosed for refurbishing sorbent materials. In one implementation among multiple implementations, a medical fluid delivery method includes: providing a sorbent cartridge including H.sup.+ZP within a casing for a treatment; and after the treatment, refurbishing the H.sup.+ZP while maintained within the casing via (i) regenerating the non-disinfected H.sup.+ZP by flowing an acid solution through the casing, (ii) rinsing the regenerated H.sup.+ZP while maintained within the casing, (iii) disinfecting the regenerated and rinsed H.sup.+ZP by flowing a disinfecting agent through the casing, and (iv) rinsing the regenerated and disinfected H.sup.+ZP while maintained within the casing. Multiple batch sorbent refurbishing implementations are also disclosed.

A detachable module for optionally recharging sorbent materials, including zirconium phosphate, with an optional bypass and conduits for a sorbent cartridge. The sorbent cartridge can have one or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein recharged.

A getter assembly for a vacuumed compartment having a plate. A primary getter material is deposited on the plate. A cover layer is deposited over the primary getter material on the plate.

Disclosed is a device for a solid phase extraction comprising two or more of the sorbents to remove phospholipids and salts from a sample, to thereby eliminate matrix effects during mass spectrometry analysis. In particular, the sorbents includes at least one sorbent which is water-wettable and contains at least one hydrophobic component and at least one hydrophilic component and at least one of sorbent having a specific affinity for a matrix interference like phospholipids. Further disclosed is a method using the device of the present invention.

A separation medium for removing small molecules from biomacromolecule in aqueous mixtures comprises gel filtration chromatography beads having a nominal protein fractional range of about 1000 Da to about 5000 Da and having an internal adsorbent matrix derived from a hydrophobicized scaffold. The gel filtration chromatography beads remove small molecules that are less than 1500 Da and have log Pow values greater than about −0.5 from biomacromolecules in aqueous mixtures. Devices containing the separation medium are also provided.

A gas separation unit for the separation of carbon dioxide from air is proposed for use in a cyclic adsorption/desorption process and using a loose particulate sorbent material. Sorbent material is arranged in at least two stacked layers, and each layer comprises two sheets of a flexible fabric material which is gas permeable but impermeable to the loose sorbent material. The sheets are arranged parallel defining an inlet face and an outlet face, are arranged with a distance in the range of 0.5-2.5 cm, and are enclosing a cavity in which the sorbent material is located. Said layers are arranged in the unit such that the inflow passes through the inlet face, subsequently through the particular sorbent material located in the cavity of the respective layer, subsequently to exit the layer through the outlet face to form the gas outflow.

Provided is a moisture absorbing material, a dehumidifying device, and a dehumidifying method each of which makes it possible to efficiently release absorbed moisture without use of a large quantity of heat. A moisture absorbing material (22) (i) having (a) a first state in which the moisture absorbing material (22) is capable of absorbing moisture and (b) a second state in which the moisture absorbing material (22) releases the moisture absorbed in the first state and (ii) having a property of changing from the first state to the second state in response to an external stimulus and returning from the second state to the first state when the external stimulus disappears, the moisture absorbing material (22) including: first through fourth moisture absorbing bodies (22a) through (22d) which have respective different stimulus response levels and are provided in order of stimulus response level so as to be in contact with one another.
