We see from your search that you're looking for information on the term "Conductivity Measurement",
and we have a large number of manufacturers' news releases and technical articles here on Laboratorytalk which will be of interest.
Let me be your guide.
Start with
the news release Online guide to conductivity theory from
QCL Scientific, which we summarised at the time by saying "QCL has made some of its extensive knowledge available on its website, where there are pages covering the basic principles and chemistry of conductivity, as well as pH and dissolved oxygen
theory".
A couple of weeks before,
we featured the news release Analysis of water hardness by automated titration from
Metrohm UK: "The major contributors to the hardness of a water sample are generally regarded as dissolved calcium and magnesium ions, which combine with soap to form insoluble precipitates".
In June 2007, we covered the news from Metrohm UK
concerning its Application bulletins 204 and 141
- take a look at Application monographs on edible oils analysis
which says: "The Rancimat method is considerably less costly, less labour-intensive but as accurate as the traditional active oxygen method (AOM) for the oxidation stability index (OSI) of natural fats and oils".
Take a look also at the news release from Metrohm UK, Broad spectrum antibiotic analysis by IC,
as well as Pure and simple, accurate conductivity measurement from Endress + Hauser,
and Liquiline M: simplicity comes as standard from Endress + Hauser.
