Automated calibrating a chromatography system and analysis of a sample

An automated method of calibrating a chromatography system and analyzing a sample is described. The method includes forming diluted standard solutions that are injected into a chromatography column. The detected peaks can be identified based on a first predetermined calibration ratio associated with the standard solution. Once the chromatography system... Dionex Corporation

Replaceable emitter assembly for interfacing a separation column to a mass spectrometer

An electrospray emitter assembly for interfacing a separation column to a mass spectrometer is disclosed. An emitter capillary includes an inlet end and an outlet end. A fitting is coupled to the inlet end of the emitter, configured to be removably connected to the separation column. A stop with a... Dionex Corporation

Chromatographic material having improved ph stability, preparation thereof and uses thereof

A chromatographic material including a substrate having a surface and having a polymeric layer covalently bound to the surface; the polymeric layer comprising polymer molecules covalently attached to the surface of the substrate, each polymer molecule being attached to the surface via multiple siloxane bonds and each polymer molecule being... Dionex Corporation

Charge reversible ion exchange resins, chromatography column, method, and system thereof

An ion exchange chromatographic packing material is described that includes a copolymer grafted to support resin particles. The copolymer includes an ion exchange group, an ionic crosslinking group configured to ionically bind to the ion exchange group, and an adjustable ionization state group having at least a first net charge... Dionex Corporation

Analyte concentrator system and methods of use

Systems and methods for concentrating an analyte preparatory to analysis thereof include processing the effluent of an analyte concentrator to produce an eluent for eluting an analyte retained in the same or separate concentrator, and systems implementing the same. The analyte concentrator system connects the effluent outlet of an analyte... Dionex Corporation

A multi-lumen mixing device is described. The multi-lumen mixing device includes a mixer body having an inlet portion and an outlet portion. The multi-lumen mixing device also includes an array of capillary channels within the mixer body, in which each capillary channel has approximately a same length. An inlet for... Dionex Corporation

Ion exchange foams to remove ions from samples

A method of making an ion exchange foam is described. The method includes forming an aqueous phase by suspending an ion exchange resin in an aqueous solvent. An organic phase is formed by mixing at least a divinylbenzene, a monomer, and a surfactant. The formed aqueous phase is mixed with... Dionex Corporation

Three-electrode buffer generator and method

An electrodialytic buffer generator is described. The buffer generator may include a central buffer-generating channel having an inlet and outlet, a second chamber, and a third chamber. The buffer-generating channel, the second chamber, and the third chamber may each include an electrode. The buffer generator may also include a first... Dionex Corporation

Method of packing chromatographic columns, packed chromatographic columns for use at high pressures and uses thereof

A method of packing a chromatography column, including: dispersing chromatographic media particles in a slurry solution to form a slurry, filling a chromatography column with the chromatographic media particles by introducing the slurry to the column and applying a pressure to pack the chromatographic media particles in the chromatography column.... Dionex Corporation

Systems and reducing signal noise due to pump oscillations

A system reduces unwanted noise due to pump movement. The system includes a pump including a non-conductive piston extending into a pumping chamber for pumping the sample fluid along an analysis fluid path, a wash chamber, and a seal fluidly separating the pumping chamber from the wash chamber. The system... Dionex Corporation

Ion-exchange composition comprising a complex of support particles, dispersant, and electrostatically bound layering particles

An ion-exchange composition suitable for use in ion exchange chromatography, comprising neutral vinyl polymer support particles irreversibly bound to a dispersant having ionizable sites which are un-ionized at a neutral pH and which are ionized under highly acidic or highly basic conditions, and fine layering particles functionalized with ion-exchanging sites...
