  2. Multicolumn countercurrent solvent gradient purification

    en.wikipedia.org/wiki/Multicolumn_countercurrent...

    Some columns are connected directly, so that non pure product streams are internally recycled. Other columns are short circuited, so that they operate in pure batch mode. The system is split into several sections, from which every section performs a tasks analogous to the tasks of a batch purification.

  3. Simulated moving bed - Wikipedia

    en.wikipedia.org/wiki/Simulated_moving_bed

    In manufacturing, the simulated moving bed (SMB) process is a highly engineered process for implementing chromatographic separation. It is used to separate one chemical compound or one class of chemical compounds from one or more other chemical compounds to provide significant quantities of the purified or enriched material at a lower cost than could be obtained using simple (batch ...

  5. Functional structuralism - Wikipedia

    en.wikipedia.org/wiki/Functional_structuralism

    Functional structuralism is a spin-off from systems theory in sociology. Systems theory, following Talcott Parsons, began as a structural-functionalist theory, that is, social structures were stressed and placed at the center of analysis, and social functions were deduced from these structures. In functional-structuralist theory, in contrast ...

  6. Soxhlet extractor - Wikipedia

    en.wikipedia.org/wiki/Soxhlet_extractor

    A Soxhlet extractor has three main sections: a percolator (boiler and reflux) which circulates the solvent, a thimble (usually made of thick filter paper) which retains the solid to be extracted, and a siphon mechanism, which periodically empties the condensed solvent from the thimble back into the percolator.

  7. Molecular distillation - Wikipedia

    en.wikipedia.org/wiki/Molecular_distillation

    Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still. [1]

  8. Process analytical technology - Wikipedia

    en.wikipedia.org/wiki/Process_analytical_technology

    PAT is a term used for describing a broader change in pharmaceutical manufacturing from static batch manufacturing to a more dynamic approach. It involves defining the Critical Process Parameters (CPPs) of the equipment used to make the product, which affect the Critical Quality Attributes (CQAs) of the product and then controlling these CPPs ...

  9. Pure sociology - Wikipedia

    en.wikipedia.org/wiki/Pure_sociology

    Pure sociology explains social life with its social geometry. [9] Social life refers to any instance of human behavior—such as law, suicide, gossip, or art — while the social geometry of a behavior, also called its social structure, refers to the social characteristics of those involved—such as their degree of past interaction or their level of wealth.
