摘要:
The present invention comprises a method for expediting the analysis of a plurality of samples, preferably using gas chromatography. A specific embodiment comprises a dual isothermal heated zone configuration for use in combinatorial chemistry. This involves partitioning the samples into two isothermal zones, allowing detailed analysis of light components in a lower-temperature zone while heavy components are handled in a higher-temperature zone.

An apparatus and a method for rapidly generating and processing a plurality of isolated effluents have been developed. A specific embodiment involves screening a plurality of solids through simultaneously contacting the members of the plurality with a fluid, sequentially sampling the resulting fluids, and processing the resulting fluids to, for example, determine changes as compared to the feed fluid or as compared to other resulting fluids.

The present invention comprises an apparatus and a method for mass analyses of an array of samples contained in distinct sample holders. The sample holders are placed on a plurality of sensors which preferably comprise an array of microbalances providing output signals comprising mass data on the array of samples.
摘要:
A process for simultaneously testing a plurality of catalysts using combinatorial chemistry has been developed. The process involves containing the plurality of catalysts in an array of parallel reactors with each reactor containing a bed of catalyst. Each bed of catalyst is then simultaneously contacted, at reaction conditions, with a reactant to form an effluent of each reactor. The reactant or an inert fluid is at a space velocity sufficient to fluidize the catalyst beds. Each of the effluents is analyzed.

A multiple parallel catalytic reactor assembly has been developed. The assembly has (1) a plurality of vessels for containing catalyst, each vessel having an open end and a fluid permeable end (2) a plurality of bottoms, each bottom having an open end and a closed end with the plurality being supported by a single first support plurality of vessels positioned within the plurality of bottoms; (3) a plurality of tops supported by a single second support with the plurality of tops engaged with the plurality of bottoms to form a plurality of sealed independent reaction chambers; (4) a plurality of first fluid conduits in fluid communication with the reaction chambers, and (5) a plurality of second fluid conduits in fluid communication with the reaction chambers.
摘要:
A reactor for conducting catalytic chemical reactions has been developed. The reactor has a well having an open end and a closed end. The reactor also has a sleeve having a top end and a bottom end. The bottom end of the sleeve is inserted within the open end of the well. A fluid permeable structure is attached to the sleeve spanning the cross-section thereby defining a chamber between the closed end of the well and the fluid permeable structure. The reactor also has a reactor insert having a fluid permeable end and a top end containing a first and a second fluid conduit. The fluid permeable end of the reactor is inserted within the open end of the sleeve. The first fluid conduit is in fluid communication with the chamber, and the second fluid conduit is in fluid communication with the fluid permeable end of the reactor insert.
摘要:
A process of forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane has been developed. A main support having at least N perforations from a first surface of the main support through a second surface of the main support in predefined locations. The main support is equipped with a flat support temporarily attached to its first surface. All samples are loaded simultaneously. A flat surface of each sample, where the flat surfaces are a common plane, is formed by forcing the samples within the perforations against the flat support. The samples are retained in position within the perforations against the flat support using at least one cover. The flat surfaces of the samples are in predefined locations and are all in a common plane.
