摘要： The present invention provides a new design for high capacity stationary phases for chromatography, for example, ion chromatography. The stationary phases include a first polymer layer in contact with and at least partially coating the substrate of the stationary phase. The first polymer layer serves as a foundation for the attachment, and in various embodiments, the growth and attachment, of a highly hyperbranched polymer structure, typically based on one or more products of condensation polymerization. Multiple components are of use in forming the first polymer layer and the hyperbranched polymer structure, thereby providing a stationary phase that can be engineered to have a desired property such as ion capacity, ion selectivity, and the like. Exemplary condensation polymers are formed by the reaction of at least one polyfunctional compound with at least one compound of complimentary reactivity, e.g., a nucleophilic polyfunctional compound reacting with an electrophilic compound.

摘要： Pretreatment method and apparatus to remove matrix ions from a liquid sample, prior to separation of the sample analytes (e.g. by chromatography), by flowing the liquid sample into a sample compartment and stopping the flow. The sample compartment has a wall comprising an ion exchange membrane having exchangeable ions of the same charge as the matrix ions to be removed. A regenerant liquid stream flows through a regenerant flow compartment on the other side of the membrane from said parked liquid sample. Matrix ions in the parked liquid sample are transported across the membrane into the regenerant flow compartment. Suppression may be performed electrolytically and/or chemically. A concentrator column may also be used.
