K0-NAA for the Determination of Trace Elements in a Synthetic Material: a Collaborative Study
As part of an interlaboratory comparison in order to certify a synthetic material to be used for the validation of the proper implementation of k0-NAA a collaborative trial was organised. Based on this collaborative study, reproducibility relative standard deviations valued ranged typically from 2 to 5%. These values were compares with the Horwitz criterium leading to HORRAT values in most cases well below 1, although two exceeding 1, depending on the element to be determined. It could be concluded that k0-NAA is a very precise method, but that still some inconsistencies for certain elements remain.
