Evaluating confidence in analytical measurement: Literature survey of sample transport & storage effects.
A review of the literature on the effects of transport and storage on chemical and microbiological measurements has been carried out and the results presented herein. The purpose of the review was to ascertain what, if any, work had been done to quantify the uncertainties arising from these effects and to use its findings to suggest areas for further experimental study. It was clear from the review that while much work has been carried out to assess the magnitudes of errors contributed by transport and storage effects, the values found have not been translated into a form that can be used directly for measurement uncertainty purposes. Since there are no obvious gaps in the coverage of sample types, it would be useful to obtain experimental data on one type of material and show how this can be used to generate sensitivity coefficients for use in measurement uncertainty calculations.
