Estimation of the uncertainty of the measurement results of some trace levels elements in document paper samples using ICP-MS
Ion Tanase,Dana Elena Popa,Gabriela Elena Udristioiu,Andrei A. Bunaciu,Hassan Y. Aboul-Enein +4 more
TL;DR: The measurement uncertainty characterizes the dispersion of the quantity values being attributed to the measurand and there are different approaches for uncertainty estimation as mentioned in this paper, however, the measurement uncertainty is defined as a measure of dispersion in the measurement results.

Evaluation and Specifications for In-Line Uranium Separations Using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) Detection for Trace Elemental Analysis:
Benjamin T. Manard,Shalina C. Metzger,C. Derrick Quarles,Kayron T. Rogers,Brian W. Ticknor,Debra A. Bostick,Eddy H. McBay,Cole R. Hexel +7 more
TL;DR: It was determined that faster exposure replicates can provide greater peak resolution with higher fidelity measurements but are limited with respect to the total analysis time (i.e., limited in detection timely separations).

Atomic and Ionic Impact Phenomena on Metal Surfaces
Manfred Kaminsky,D. Elwyn Davies +1 more
- 01 Jan 1965
Abstract: Abstract A pulsed-molecular-beam mass spectrometer has been developed, which offers a new approach in the investigations of the kinetics of gas/solid interactions and in research on molecular beams. Since the construction of the major portion of the apparatus has been completed, it seems appropriate at this time to describe the design features of the machine and to discuss briefly some particular research objectives which will be made possible by the special design features of the apparatus. It is intended to limit this discussion mainly to the types of investigations of atomic impact phenomena on metal surfaces made possible by the new design and refer to other reports [1] for discussion of ionic impact phenomena (such as inelastic and elastic reflection of ions from clean single-crystal surfaces, resonance neutralization of ions, etc.).
