(This reaction occurs under well-controlled temperature, pH, elemental ratio, and feed dilution with water).
The large variation of elemental ratio [I/(Sb + Bi)] would be attributed to the crystal segregations.
One important elemental ratio is that of [Fe/H], one of the factors determining the propensity of a region of the galaxy to produce terrestrial planets.
After elemental ratio analyses, parallel tracks were ablated on each otolith to quantify 87Sr/86Sr ratios with a Thermo Neptune multi-collector ICP-MS.
Engine load alone can affect the ratio of organic to elemental carbon in diesel PM, with a higher organic:elemental ratio at low loads (Shi et al. 2000).
The average elemental ratio was subsequently calculated from all ions in a signal-weighted way. Figure 2 compares the elemental ratios calculated from the EI spectra to the nominal values of the compounds.
The elemental ratio obtained from the analysis of high-resolution (XPS) spectra is Ti3C2.2O2F0.6 (see Supporting Information section II).
The heuristic filters employ the LEWIS and SENIOR chemical rules, accuracy of isotopomer abundance patterns, elemental ratios, elemental ratio probabilities, the presence of derivatizable functional groups, and the presence of elemental formulas in the PubChem database (http://pubchem.ncbi.nlm.nih.gov/).nih.gov/
The elemental ratio obtained from the analysis of high-resolution XPS spectra (see Supporting Information section II) of Ti3C2 produced by NH4HF2 etching is Ti3C2.3O1.2F0.7N0.2.
For accurate quantitative analysis, the elemental ratios should be stable over the entire reduction period.
This table contains foraminifera-based stable isotope results, relative sample ages, selected elemental ratios as well as the calculated mixed layer pH.
