  • solid phase extr
  • Solid-phase microextraction, or SPME, is a solid phase extraction sampling technique that involves the use of a fiber coated with an extracting phase, that can be a liquid (polymer) or a solid (sorbent), which extracts different kinds of analytes (including both volatile and non-volatile) from different kinds of media, that can be in liquid or gas phase. (wikipedia.org)
  • Analytical laboratories use solid phase extraction to concentrate and purify samples for analysis. (wikipedia.org)

  • practitioners
  • Modern advances in nuclear and radiochemistry research have allowed practitioners to apply chemistry and nuclear procedures to elucidate nuclear properties and reactions, used radioactive substances as tracers, and measure radionuclides in many different types of samples. (wikipedia.org)
  • mass
  • Gravimetric techniques use precipitation or volatilization to determine the mass of the analyte from its ionic mass. (news-medical.net)
  • Coulometric techniques: This set of techniques helps to determine the mass of matter transformed by electrolysis from the amount of electric current used or produced during the reaction. (news-medical.net)
  • In 2002, Koichi Tanaka, a longstanding employee, won the Nobel Prize in Chemistry for developing a method of mass spectrometric analysis of biological macromolecules. (wikipedia.org)
  • molecular
  • Host-guest chemistry encompasses the idea of molecular recognition and interactions through noncovalent bonding. (wikipedia.org)
  • Host-guest chemistry is observed in inclusion compounds, Intercalation compounds, clathrates, and molecular tweezers. (wikipedia.org)
  • Instrumental
  • Instrumental techniques are increasingly employed at higher levels of research, and the same instrument is often sufficient to separate, identify and quantitate the analyte. (news-medical.net)
  • Clinical
  • In the multivariate module one can choose between three different techniques - SVM (support vector machine), PLS-DA (partial least squares discriminant analysis) and Random Forests for classifying and selecting metabolites or clinical variables for an optimal ROC performance. (wikipedia.org)
  • commonly
  • The most commonly used technique for the extraction of a compound from an aqueous solution is liquid-liquid extraction (LLE). (news-medical.net)
  • Conventional X-ray generators are most commonly used, because their output can readily be "tuned" for the application, and because higher power can be deployed relative to other techniques. (wikipedia.org)
