Total Sample Evaporation of 1 ng SRM U350 - Precision and Accuracy by Static Faraday Cup Multicollection

Dietmar Tuttas

Thermo Fisher Scientific, Bremen, Germany

AN30017

Goal: This report described the use of "Total Evaporation" to obtain high precise and accurate U isotope ratio data. During total sample evaporation, a sample is continuously and completely evaporated from the filament.
