About Speciation



Books on Elemental Speciation
The following list gives some details on books devoted to elemental speciation (analysis) published since 2001. The list is neither exhaustive nor do we guarantee that all books are still available. ...

Certified Reference Materials for Speciation Analysis
Certified reference materials are a major tool for laboratories to monitor the performance of their analyical work. Similarly to other measurement fields, speciation analysis requires the availability...

Directory of scientists
You may search for a name, an institution, an address, a research interest or available instrumentation. Alternatively you may browse the directory of scientists sorted alphabetically by family names...

Don't miss these deadlines !!
Deadlines coming soon, coming later or already gone....

History of Speciation Conferences
While there are many conferences and symposia having sections on speciation analysis, there a few totally dedicated to speciation analysis. Following these conference is helpful for the understanding ...

How did elemental speciation develop ?
The rapid development of inorganic instrumental analysis after World War II, mainly driven by the development of atomic spectrometry, enabled the analytical community to look into the role of trace el...

Problems to be solved
The major challenge of speciation analysis is the isolation, separation and quantification of the species leaving the original compound intact, which may be in some kind of equilibrium state with othe...

REACH: Registration, Evaluation and Authorisation of Chemicals
The European Commission proposed a new EU regulatory framework for the Registration, Evaluation and Authorisation of Chemicals (REACH) on 29 October 2003.     Aims of REACH The aim is to im...

Research fields related to elemental speciation
The research fields for speciation analysis are manifold and cannot be discussed in detail here. However some major fields should be mentioned: Environmental risk analysis with its main tasks hazard ...

Speciation analysis as a tool to enhance the quality of life
Speciation analysis provides the information necessary to describe the effects of active species ( Why should it be done ?) which is not available from the results of total trace element determination...

Speciation and Toxicity
In classical toxicology, speciation of carbon is taken for granted and the carbon compounds responsible for toxicity are always described with the appropriate chemical nomenclature. By contrast, speci...

Speciation as a discipline in Analytical Chemistry – Definitions
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...

Speciation Events

Speciation News

Species of interest
Depending on the area of interest, speciation analysis is focussing on chemical compounds that differ in isotopic composition, conformation, oxidation or electronic state, or in the nature of their co...

The role of elemental speciation in legislation
Our understanding for the mechanisms of biological activities and biogeochemical cycling of mineral and trace element species has been substantially advanced during recent years with the help of chemi...

Tools for elemental speciation
The tools for speciation analysis are manifold. Very few species-specific techniques do, however, allow direct speciation. These include Mössbauer spectroscopy, X-ray photoelectron spectroscopy, Nucle...

Vacancies
Under the sections below we report about open positions related to speciation analysis that have been announced to us. If you have such information that you would like to share with the community of...

What is the use for total element concentrations ?
Since only speciation analysis provides the information about the identity of chemical species and there concentration, the question about the value of the often performed "total element determination...

Why is elemental speciation not done routinely ?
  Historically trace metal and non-metal analyses have mainly evolved through the development of atomic spectrometry after world war II. Unfortunately, sources for atomic spectrometry (atomizers...

Why should elemental speciation be done ?
Whenever an analyst is producing data on the presence and/or concentration level of elements in a sample, the data are meant to answer one of the following questions depending on the nature of the sam...
