New application note on the downloads page – Measurement of NBS U010, NBL U030a and NBL U050 uranium standards by total evaporation using the Phoenix TIMS.

This note describes the performance of the Phoenix TIMS for total evaporation of small U loads using three CRM’s. Total evaporation removes the need for a mass fractionation correction since ions from across the entire run are collected and summed. The note highlights the Phoenix’s ability to attain precision of 0.03% or better for 235U/238U on sample loads of 200ng. This note will be of interest to anyone who needs to routinely analyze small U samples.
