PCA is a mathematical method of reorganising information in a data set of samples. It can be used when the set contains information from only a few variables but it becomes more useful when there are large numbers of variables, as in spectroscopic data.
I asked the European RM producer if they thought an improvement was needed in the level of awareness about the proper use of reference materials in analytical laboratories. I asked the basic questions I’d asked RM users two years ago.
Trilinear fluorescence spectroscopy is emerging as one of the most powerful techniques to study chemical equilibria, monitor chemical reactions and to analyse test samples. But what is trilinear fluorescence spectroscopy?
