A mass-spectrographic study of the isotopic constitution of Sr, Ba, Bi, and Tl has been made. Although the sensitivity and resolving power of the apparatus were sufficient to detect extremely rare isotopes, no new ones were found. Relati... Nier,O Alfred - 《Physical Review》 被引量: 149...
For 20 μl of sample (wine+0.056 mol l−1 HNO3, 1+1, v/v) dispensed into the graphite tube, analytical curves in the 0.10–1.0 μg l−1 Cd and 5.0–50 μg l−1 Pb ranges were established. The characteristic mass was approximately 0.6 pg for Cd and 33 pg for Pb, and ...
Here the reversible deposition and dissolving of atomic Sn on the Cu electrode was directly confirmed by the EQCM characterization. As shown, the mass on the electrode presented a clear and sharp increase as a result of the Sn deposition and then gradually decreased to the original value because...

Mass aliquots between 0.8 and 1.0 mg were weighed and directly inserted into the graphite furnace. The precision (expressed as RSD) was lower than 5%, and a detection limit of 2.16 pg was obtained at the 283.306 nm resonance line. The limit of quantification was 7.2 pg. The Pb recuperation...
The described method has been validated by analyzing certified reference material (BCR-CRM 150) and by comparing the results with those obtained by inductively coupled plasma mass spectrometry (ICP-MS). The validated method was applied to raw cow's milk samples produced in 7 different regions of...
PLASMA-MASS SPECTROMETRYWHOLE-BLOODETAAS METHODCADMIUMELEMENTSLEADPBDEFICIENCYFRACTIONSCHROMIUMA graphite furnace atomic absorption spectrometric method is proposed for the direct and simultaneous determination of Cd, Cu, and Se in human blood.

The detection limit (3s) is 0.6 µg g–1 dry mass. Typical day-to-day precision is < 5%. Method accuracy is established as better than 1% using NIST SRM 1400 Bone Ash and SRM 1486 Bone Meal, which are the only reference materials we have found for bone-Pb measurements. The method...
