An analytical technique is a method for the analysis of some problem, status, or fact. Analytical techniques are normally time-limited and task-limited. They are used once to solve a particular issue.
Analytical technique is a method that is used to define a chemical or physical property of a chemical substance, chemical component. There is a broad class of techniques employed for analysis, from simple weighing (gravimetric analysis) to titrations (titrimetric) to very advanced techniques using highly specialized instrumentation. The most frequent techniques used in analytical chemistry are the following:
Titrimetry, based on the quantity of reagent required to react with the analyte
Electroanalytical methods, including potentiometry and voltammetry
Spectroscopy, based on the differential communication of the analyte along with electromagnetic radiation
Chromatography, in which the analyte is isolated from the rest of the sample so that it may be covered without interference from other compounds
