Abstract: A sensitive analytical procedure based on nano-volume flow injection (FI) and inductively coupled plasma double-focusing sector field mass spectrometry (ICP-SFMS) was developed for the ultratrace determination of uranium and plutonium. A 54-nl sample was injected by means of a nanovolume injector into a continuous flow of carrier liquid at 7 mul min(-1) prior to ICP-SFMS. The absolute detection limits were 9.1 x 10(-17) g (3.8 x 10(-19) mol, similar to230 000 U-238 atoms) and 1.5 x 10(-17) g (6 x 10(-20) mol, similar to38 000 Pu-242 atoms) for uranium and plutonium, respectively. The method was validated for the determination of the uranium isotope ratios by the analysis of a certified isotope reference material (NIST U350). The analysis of a contaminated urine sample showed the enriched uranium to be the origin of contamination. Another application concerned the determination of plutonium at the subfemtomolar level in water with a detection limit down to the ag ml(-1) range ( 6 x 10(-18) g ml(-1)).
