Abstract: Gas chromatographs of the invention generally comprise four or more analysis channels. Specifically, four or more gas chromatography columns are configured for parallel analysis of four or more gaseous samples with detection being effected using a microdetector array comprising four or more microdetectors. In one embodiment, the four or more microdetectors 510 are microfabricated detectors, and are integrally formed with a substrate or with one or more microchip bodies mounted on a substrate. In a preferred embodiment, a microdetector array comprises four or more thermal conductivity detectors having one or more thin-film detection filaments. A preferred heated environment for highly parallel gas chromatographs is also disclosed.

Abstract: One aspect of the present invention provides instruments for measuring mechanical properties of a combinatorial library of materials. The instruments include at least one capacitor to which a member of a library of material samples is removably secured for testing; at least one voltage source for delivering one or more forces to each library member; and at least one sensing device for monitoring the response each library member to the one or more forces. Another aspect of the present invention provides methods of screening a combinatorial library of materials where the method monitors the responses of a plurality of samples on a substrate to a force induced by a capacitor.
