aliquot: (analytical chemistry) A known amount of a homogeneous material, assumed to be taken with negligible sampling error The term is usually applied to fluids. The term "aliquot" is usually used when the fractional part is an exact divisor of the whole; the term "aliquant' has been used when the fractional part is not an exact divisor of the whole. When a laboratory sample or test sample is 'aliquoted' or otherwise subdivided, the portions have been called split samples. [IUPAC Compendium]

autosampler: Automated sample loader, usually robotic, used  with chromatography and other analytical technologies.

biocatalysis: The application, both actual and potential, of biological catalysts (including whole cells or isolated components thereof, natural and modified enzymes and catalytic antibodies) for the synthesis, interconversion or degradation of chemical species. In addition to papers describing the synthetic applications of biotransformations the journal particularly welcomes papers focusing on the mechanistic principles, kinetics and thermodynamics of biocatalytic processes, the chemical or genetic modification of biocatalysts and the activity and stability of biocatalysts in non- aqueous and multi- phasic environments, including the design of large scale biocatalytic processes. The scope of the journal also encompasses biomimetic systems and environmental applications of biocatalysis where the mechanistic principles are understood or novel biocatalytic activities are involved. [Biocatalysis and Biotransformation, Aims and scope,  Taylor & Francis] http://www.tandf.co.uk/journals/titles/10242422.html

Related terms: biotransformation; Biomaterials  biomimetic

bioreactors: Tools or devices for generating products using the synthetic or chemical conversion capacity of a biological system. They can be classical fermentors, cell culture perfusion systems, or enzyme bioreactors. For production of proteins or enzymes, recombinant microorganisms such as bacteria, mammalian cells, or insect or plant cells are usually chosen. MeSH 1997

PAT Process Analytical Technology: A system for designing, analyzing, and controlling manufacturing through timely measurements (i.e., during processing) of critical quality and performance attributes of raw and in-process materials and processes with the goal of ensuring final product quality. It is important to note that the term analytical in PAT is viewed broadly to include chemical, physical, microbiological, mathematical, and risk analysis conducted in an integrated manner. .. There are many current and new tools available that enable scientific, risk-managed pharmaceutical development, manufacture, and quality assurance...  In the PAT framework these tools can be characterized as Multivariate data acquisition and analysis tools, Modern process analyzers or process analytical chemistry tools, Process and endpoint monitoring and control tools, Continuous improvement and knowledge management tools. An appropriate combination of some, or all, of these tools may be applicable to a single-unit operation, or to an entire manufacturing process and its quality assurance. Product and Process Development Group Meeting of the PAT Subcommittee, CDER, FDA, Gaithersburg MD, June 12- 13, 2002 http://www.fda.gov/ohrms/dockets/ac/02/minutes/3869M1_01_PATSubcommittee-Product-ProcessWG.pdf

A system for designing, analyzing, and controlling manufacturing processes through timely measurements (i.e., during processing) of critical quality and performance attributes of raw and in-process materials, to ensure final product quality. The term analytical in PAT is viewed broadly to include chemical, physical, microbiological, mathematical, and risk analysis conducted in an integrated manner. The emphasis in PAT is on the manufacturing process to amplify the basic premise of the current drug quality system: Quality cannot be tested into products; it should be built-in or should be by design.

process chemistry:  A list of terms with their definitions used in "Process Chemistry/Manufacturing of Active Pharmaceutical Ingredients" and "Pharmaceutics"; About 850 terms directly related to each of the fields of "Process Chemistry/Manufacturing of Active Pharmaceutical Ingredients" and "Pharmaceutics"; will be compiled and defined by this expert group for dissemination to the scientific community. This will help achieve a common definition base across the various publications in this field. In addition, a more uniform use of these terms should assist in the future construction of glossaries pertaining to this continually evolving field's information.
