Optical emission spectrometers (OES) and the measuring principle of the atomic emission are the ideal method and provide the perfect instrumentation for metal analysis in all different industrial businesses and environments. Q2 ION The Q2 ION is one of the smallest and lightest ultra-compact spark ...
(two to five atoms),optical spectroscopyrepresents the gold standard for both breath analysis as well as for other trace gas applications. If the chemical identity of the breath biomarker is known and the molecule exhibits well-defined absorption features, in principle, it is quite straightforward ...
Emission line intensities are interpreted using a model of the important collisional and radiative processes occurring in the plasma. The model examines secondary processes such as radiation trapping, excitation transfer between levels of the carne principle quantum number, and excitation front metastable ...
An optical source is used to interact with the medium for all diagnostics other than optical emission spectroscopy (OES) and pyrometry. The optical signal is spectrally analyzed, either before or after this interaction, and then is detected to give an electronic signal that is interpreted. Demt...
A laboratory test of Einstein's equivalence principle in atomic dysprosium: Search for temporal and gravitational variation of the fine-structure constant Nearly degenerate, opposite-parity levels of atomic dysprosium are highly sensitive to variation of the fine-structure constant, 伪, due to large re...
The intuitive picture of the operation principle shown in Fig. 1 highlights the time-to-frequency mapping process, as well as the main design trade-offs in the system. In particular, the scaling law of the implemented time-to-frequency mapping process is simply defined by the ratio fs/τc....
1e, and “Methods” for imaging principle)33. The FFT image provides size, charge, and mobility of the protein as we show below. Fig. 1: Imaging single proteins and mechanical oscillations. a Proteins are tethered to an ITO surface with a flexible polymer tether, and driven into ...
This principle is shown in Figure 36. In the presence of a nonspecific or noncomplementary DNA strand, the DNA forms an electrostatic interaction with the polyfluorene, but the distance from the PNA is too large to allow FRET. Several variations on this theme allowing detection of RNA, double...
The use of the signal diversity principle through creating multiple independent beams significantly reduced the probability of signal drop-outs in the optical heterodyne detection. These systems have found many practical applications, and most of them have been applied commercially, giving a broad range...
