WebA method of surface analysis by nonresonant multiphoton ionization is described and illustrated with an example of analysis consuming ~10−15 gram of a uranium compound (~10−17 mole). The method is chemically general and quantitative for elemental analysis without specially prepared standards. In this method desorbed, sputtered, or evaporated … Webpretation of the MPI results. The success ofMPI as a method for preparing reactant ions is based on the degree to which ions can be produced with a narrow and known distribution of internal energies. The fulfillment of this requirement depends on the precise mechanism of ionization by multiphoton adsorption. In par-
Web18 nov. 2024 · Zstar, here, is not the actual ion charge. It is used to test the cumulative ionisation probability for each charge state. The ion is not always ionised (only when U2 < We/Wi) because it is a Monte Carlo approach to particles having different weights. It is true that the order of loops and ifs is not optimal here. Web10 ian. 2013 · Multiphoton ionization/time-of-flight mass spectrometry (MPI/TOFMS) was modified for the rapid analysis of gasoline-contaminated soil. This technique uses a nanosecond laser emitting at 266 nm, and has the potential to produce the mass spectrum for gasoline 30 min after sampling. The rapidity and robustness of the method can be …
