Sample Homogeneity and Stability Evaluation
Here are presentations on sample homogeneity and stability monitoring. Of particular interest is a pseudo homogeneity/stability check we have established for every sample.Homogeneity Monitoring.
Documents published by The Analytical Methods Committee of The Royal Society of Chemistry
Here are selected short supporting documents. There is a great deal of literature describing the applications of Robust Statistics over an extremely diverse range of subjects. John Tukey, Peter Huber and Frank Hampel have been credited with founding the discipline and all this since the landmark paper by Tukey in 1960. So, you can see that this is a fairly young science nevertheless, the literature and bookshelves are rife with the subject.Analytical Methods Committee 2 page Technical Brief describing the Robust Calculations used in the IHP and ISO 13528.
Analytical Methods Committee 2 page Technical Brief on representing data distributions with kernel density estimates.
Analytical Methods Committee 2 page Technical Brief describing and using the "Fitness for Purpose" criterion.
