    A quantitative study of the determination of halides and halogenic anions by negative ion electrospray mass spectrometry (ES-MS) is presented. Calibration plots were found to be linear over a range of –4 orders of magnitude for F-, Cl-, ClO3-, ClO4-, Br-, I-and IO3- . Electrospray ionization of alkali halide solutions in the negative ion mode results in the formation of cluster ions of the general formula, (MX) n X −.However, alkali iodides form triiodide anion, I 3 −, in high abundance in addition to cluster 3 − ions are observed in low abundance. Also, mixed tri-halide anions, I 2 Y −, are observed in high abundance when a small amount .

Michael: Affiliation: AA(Stanford Research Institute, Menlo Park, California), AB(Stanford Research Institute, Menlo Park, California) Publication: The Journal of Chemical Physics, Vol Issue 6, p (JChPh Homepage. Mass spectrometry is an analytic method that employs ionization and mass analysis of compounds in order to determine the mass, formula and structure of the compound being analyzed. A mass analyzer is the component of the mass spectrometer that takes ionized masses and separates them based on charge to mass ratios and outputs them to the.

In each instance, ∼1% dimer and % trimer were observed. Heats of sublimation have been measured by second‐ and third‐law methods. The discrepancy between the two methods varies from 2 kcal/mole for MgI2 to 5 kcal/mole for MgF2, with the third‐law Cited by:   Mass‐Spectrometric Study of the Vaporization of Lithium and Sodium Metaborates J.

From physical chemistry to mass spectrometry to government lab manager in half a century. Introduction. In the first part of this work we presented the characteristic fingerprint of alkali and alkaline earth chromate, as obtained after laser ablation/ionization by time-of-flight mass spectrometry (TOF-LMMS) and Fourier transform ion cyclotron resonance mass spectrometry (LA-FTICRMS).

These preliminary results allowed us to elaborate on the specific behavior of (1) alkali. The appearance of this type of peak arrangement at the high end of the m/z scale on the mass spectrum is characteristic of the molecular ion. The two higher mass peaks are due to the presence of isotopes of the compound's atoms.

The ratio found in the peak pattern is the result of natural isotope abundance of the atoms in the molecule. On Lattice Parameters and Enthalpies of Mixing of Alkali Halide Solid Solutions. physica status solidi (b)(1), DOI: /pssb Mirosław Miller, Krzysztof Skudlarski.
