Title: Terminology for the description of peak asymmetry in
chromatography
Task Group
Chairman: Jan Åke
Jönsson
Member: Roger
M. Smith
Completion Date: 2006
Objective:
To make recommendations of definitions and terms for the description
of the symmetry of peaks in chromatography separations.
Description:
The aim is to clarify the range of terms used to define the shape
of peaks following chromatographic separations. Currently the different
expressions and definition can cause confusion and ambiguity. Different
data handling systems can report different values for the same peaks
because different calculation methods have been employed. The project
with bring together views from interested parties and recommend terms
and definitions to be used.
Progress:
Two letters to editors describing the problem of asymmetry calculation
ambiguity and inviting to discussion were published:
J.Å. Jönsson , Towards a consensus on calculating peak asymmetry.
LCGC North America, 2002, 20:920 and LCGC Europe,
2002, 16:772. As a result, a number of e-mails were received,
unfortunately not providing a clear consencus on the matter. A final
report is in preparation.
