analysis definition chemistry
The International Union for Pure and Applied Chemistry (IUPAC) has published guidelines or recommendations for the definition of speciation analysis: Speciation analysis is the analytical activity of identifying and/or measuring the quantities of one or more individual chemical species in a sample. analysis, chemical: see chemical analysischemical analysis, the study of the chemical composition and structure of substances. More broadly, it may be considered the corpus of all techniques whereby any exact chemical information is obtained. Definition of analysis. analyses. Examples of analysis in a sentence. His analyses expose hidden fractures with the clarity of an X-ray, and his rhetorical skill, though modulated in a journalistic style, owes much to the give and take of Euripides' crisp dialogue. Definition of analysis for English Language Learners. : 1  a careful study of something to learn about its parts, what they do, and how they are related to each other. : 2  an explanation of the nature and meaning of something. Definition of analysis. plural. analyses. play \-ˌsēz\. 1a : a detailed examination of anything complex in order to understand its nature or to determine its essential features : a thorough study doing a careful analysis of the problemb : a statement of such an examination. chemical analysis, the study of the chemical composition and structure of substances. More broadly, it may be considered the corpus of all techniques whereby any exact chemical information is obtained. There are two branches in analytical chemistry: qualitative analysis and quantitative analysis. chemical analysis - the act of decomposing a substance into its constituent elements. qualitative analysis. analysis - an investigation of the component parts of a whole and their relations in making up the whole. uranalysis, urinalysis - (medicine) the chemical analysis of urine (for medical diagnosis) Speciation as a discipline in Analytical Chemistry  Definitions. Speciation analysis is the analytical activity of identifying and/or measuring the quantities of one or more individual chemical species in a sample. The chemical species are specific forms of an element defined as to isotopic composition, electronic or oxidation state, and/or complex or molecular structure. quantitative analysis, quantitative chemical analysis - chemical analysis to determine the amounts of each element in the substance. spectrographic analysis, spectrometry, spectroscopic analysis, spectroscopy, spectrum analysis - the use of spectroscopes to analyze spectra. Qualitative Analysis Definition: The determination of the nature of the chemical species in a sample. Qualitative analysis can tell you whether an atom, ion, or compound is present or absent in a sample, but it does not provide information about its quantity (how much). Qualitative analysis is a set of analytical chemistry techniques. It involves chemical tests, such as the Kastle-Meyer test for blood or the iodine test for starch. Another common qualitative test, used in inorganic chemical analysis, is the flame test.
The study of the chemical composition and structure of substances.
