Chemometrics and standards
Standards are central to the achievement and maintenance of accuracy in trace analysis. This fact is well-known and well-accepted in the international analytical chemical community, where "standards" are generally considered to be Standard Reference Materials (SRMs) or Certified Reference Materials (CRMs). The term, standards, however, is multivalued, as noted recently by a former Director of t...
متن کاملChemometrics in Food and Beverage
Scientists in the food and beverage industry are faced with many different quality control tasks, such as making sure that flavors meet certain standards, identifying changes in process parameters that may lead to a change in quality, detecting adulteration in any ingredient and identifying the geographical origin of raw materials. Food scientists who work for regulatory agencies, such as the F...
متن کاملChemometrics in Environmental Science
Scientists involved in environmental studies are faced with many different analytical tasks, such as assembling baseline studies, evaluating the contributing influence of chemical discharge to complex natural systems, and modeling biological response. Industrial scientists are concerned with the mechanics of recycling materials and maintaining process control systems that minimize pollution. Go...
متن کاملChemometrics: an overview.
Chemometrics is broadly defined as the application of mathematical and statistical methods to chemistry. Because the mathematical and statistical aspects of chemistry require measured values, analytical chemists have been at the forefront of the "chemometric revolution." Using the analysis of variance as a paradigm, I present an overview of chemometrics as it is practiced today. Receiving speci...
متن کاملChemometrics in metabonomics.
We provide an overview of how the underlying philosophy of chemometrics is integrated throughout metabonomic studies. Four steps are demonstrated: (1) definition of the aim, (2) selection of objects, (3) sample preparation and characterization, and (4) evaluation of the collected data. This includes the tools applied for linear modeling, for example, Statistical Experimental Design (SED), Princ...
