@article{JRC14850, address = {}, year = {1998}, author = {Lamberty A and Schimmel H}, abstract = {Isochronous measurements are based on a storage design (storing samples at different temperatures for different time periods) allowing all measurements to be done at the same time i.e. at the end of the study. This method is compared to "classical" designs of stability studies using reference time or reference temperature. The execution of stability studies using "isochronous" measurements only requires repeatability conditions contrary to the other designs which require both repeatability and long term reproducibility conditions. Consequently with the new design the quality of results can be improved. }, title = {The Study of the Stability of Reference Materials by "Isochronous" Measurements.}, type = {}, url = {}, volume = {}, number = {}, journal = {Fresenius Journal of Analytical Chemistry}, pages = {}, issn = {}, publisher = {}, doi = {} }
