| Popis: | Two foodstuffs, wheat and green coffee, have been sampled from bulk lots by multiple samplers in the sampling analogue of a collaborative trial. For wheat the variation between samplers, contributing to the standard deviation of sampling reproducibility, was significant for two analytes. No significant sampling reproducibility variation was found in the coffee results, although significant sampling repeatability variation was detected. |
