Analytical chemistry has been important since the early days of chemistry, providing methods for determining which elements and chemicals are present in the object in question. During this period, significant contributions to analytical chemistry included the development of systematic elemental analysis by Justus von Liebig and systematized ...
The Analytical Sciences Digital Library (ASDL) was founded in 2001 as one of several digital libraries in the National Science Digital Library, funded by the National Science Foundation. The library is a collection of peer-reviewed electronic resources on chemical measurements and instrumentation.
Izaak Maurits (Piet) Kolthoff (February 11, 1894 – March 4, 1993) was an analytical chemist and chemistry educator.He is widely considered the father of analytical chemistry for his large volume of published research in diverse fields of analysis, his work to modernize and promote the field, and for advising a large number of students who went on to influential careers of their own.
The Encyclopedia of Analytical Chemistry is an English-language multi-volume encyclopedia published by John Wiley & Sons. It is a comprehensive analytical chemistry reference, covering all aspects from theory and instrumentation through applications and techniques. Containing over 600 articles and over 6500 illustrations the 15-volume print ...
The general expression Qualitative Analysis [...] refers to analyses in which substances are identified or classified on the basis of their chemical or physical properties, such as chemical reactivity, solubility, molecular weight, melting point, radioactivity properties (emission, absorption), mass spectra, nuclear half-life, etc. Quantitative Analysis refers to analyses in which the amount ...
In analytical chemistry, sample preparation (working-up) refers to the ways in which a sample is treated prior to its analyses. Preparation is a very important step in most analytical techniques, because the techniques are often not responsive to the analyte in its in-situ form, or the results are distorted by interfering species.
Flow injection analysis (FIA) was first described by Ruzicka and Hansen in Denmark in 1974 and Stewart and coworkers in United States in 1979. FIA is a popular, simple, rapid, and versatile technique which is a well-established position in modern analytical chemistry, and widespread application in quantitative chemical analysis. [6]
Potentiometry passively measures the potential of a solution between two electrodes, affecting the solution very little in the process. One electrode is called the reference electrode and has a constant potential, while the other one is an indicator electrode whose potential changes with the sample's composition.
