Uncertainty on sampling - EURACHEM GUIDE
Bringing todaya very interesting issue connected with water and environmental examination.
The uncertainty from sampling is an old issue on the environmental chemistry, that ISO 17025 tryed to control using validation and chart control inside the lab. Well, EUrachem solved this problem with a simple method tha permits the analitycal system to evaluate the heterogenity of the target sample (or sample site) and understand which is the uncertainty that comes from the field and which one is from the lab.
I have more materials about. If anyone have interest, please contact me that I can supply you with those extra information.
