✦ Synopsis

Mixed-actinide microstandard particles have been produced for calibration and performance testing of isotope-ratio mass spectrometers and ion and electron microprobe instruments. The spherical micrometer-size particles consist of an aluminosilicate matrix loaded with 2.2% by weight of isotopically certified uranium and 0.11% by weight of isotopically certified plutonium. The uranium and plutonium isotopic compositions have been verified b thermal ionization mass spectrometry and secondary ionization mass spectrometry SIMS).

r both

The elemental composition of the microspheres has been determined by both electron microprobe and SIMS analysis. (

Natural water samples are normally filtered through a 0.45 pm membrane filter before analysis. Such filters clog rapidly, however, when the content of humic acids is high. An alternative approach for natural water filtration is reported in this paper. Sample solutions are pumped into tubing containi
