  • Patent number: 6410332
    Abstract: Methods and devices for rapidly analyzing groups of reactions are disclosed. The method includes the steps of contacting a fluid sample from one of the reaction mixtures with a sorbent, trapping at least one component of the fluid sample on the sorbent, and detecting the at least one component of the fluid sample trapped on the sorbent. The contacting step, the trapping step, and the detecting step are carried out at least once for each of the reaction mixtures in rapid serial or parallel fashion. The present invention is useful for screening combinatorial libraries, especially libraries of catalysts made through parallel synthesis, but the disclosed methods and devices can be used to analyze a broad spectrum of chemical transformations.

  • Patent number: 6403840
    Abstract: Olefin bromohydrins and/or alkane dibromides are reacted with metal oxide to form olefin oxides. The metal bromide is converted to form the original metal oxide and bromine, both of which are recycled.

  • Patent number: 6395552
    Abstract: The present invention discloses an apparatus and method for rapid synthesis and analysis of members of a combinatorial library. The apparatus includes a plurality of vessels for containing individual library members and a fluid handling system that apportions a test fluid about equally between each of the vessels. This allows for simultaneous screening of library members by detecting changes in test fluid following contact with individual library members. Fluid flow through each of the vessels is controlled using passive flow restrictors or active flow controllers to ensure that each library member contacts approximately the same amount of test fluid per unit time. The disclosed apparatus and method is especially useful for making inorganic oxide mixtures and for screening the mixtures based on their ability to catalyze the conversion of fluid reactants.
