SIMS: a capable method for BCN quantification
Applied Surface Science, 2000Abstract Obvious matrix effects often inhibit major component analysis carried out with secondary ion mass spectrometry (SIMS). Although MCs+ secondary ions (M represents the element to be analyzed) are used — already know as matrix independent for some compounds — feasibility of SIMS quantification has separately be validated for each new system ...

In situ U–Pb SIMS (IN-SIMS) micro-baddeleyite dating of mafic rocks: Method with examples
Precambrian Research, 2010Abstract An in situ U–Pb SIMS (IN-SIMS) method to date micro-baddeleyite crystals as small as 3 μm is presented with results from three samples that span a variety of ages and geologic settings. The method complements ID-TIMS geochronology by extending the range of dateable crystals to sizes smaller than can be recovered by physical separation. X-ray

SIM: a Korean signature extraction method
Proceedings of TENCON '93. IEEE Region 10 International Conference on Computers, Communications and Automation, 2002The signature file method has been recently thought as a useful text retrieval method when inverted file method is not available. However, traditional word-oriented signature file methods cannot retrieve all the relevant text items in the variable-spacing environment such as Korean text.

SIMS method of material wear diagnosis
2009 IEEE International Conference on Industrial Technology, 2009The presented method is based on use of SIMS analysis. SIMS analysis allowed experimental demonstration of 100 … 300 times increase in the dissolved hydrogen concentration at a depth of 1 … 20 mm in the pipe wall after 20 years of operation. The hydrogen dissolved in the pipe wall from a gas flow in a gas-main pipeline.

The infinite velocity method: A new method for SIMS quantification
Surface and Interface Analysis, 1994Abstract Twelve elements spanning a mass range of 197 atomic mass units from five standard reference materials and three implant materials were analysed to ascertain the validity of a new method, termed the infinite velocity method, for quantifying the negative monatomic secondary ion emissions resulting from Cs‐bombarded surfaces ...

SIMS and RBS analysis of leached glass: Reliability of RSF method for SIMS quantification
Journal of Materials Science: Materials in Electronics, 1996The reliability of the relative sensitivity factor (RSF) approach for secondary ion mass spectrometry (SIMS) quantification of the leached layers on glass was investigated by measuring comparable samples of glass with SIMS and RBS (Rutherford backscattering spectrometry). The RSF factors were calculated using the nominal bulk compositions.

A fast sparse iterative method (SIM) for method of moments
Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting, 2002The sparse iterative method (SIM) provides a faster solution to method of moments (MoM) matrix equations than does LU-decomposition with forward and back substitution. The SIM produces a solution with computational time proportional to N/sup 2/, as opposed to the N/sup 3/ time dependence associated with LU-decomposition.

Methods for Generating Protein Molecular Ions in ToF-SIMS
Langmuir, 2004One of the greatest challenges in mass spectrometry lies in the generation and detection of molecular ions that can be used to directly identify the protein from the molecular weight of the molecular ion. Typically, proteins are large (MW > 1000), nonvolatile, and/or thermally labile, but the vaporization process produced by many mass spectrometry ...

A NEW APPROACH OF THE SIMS METHOD FOR METAL CLUSTERS
Surface Review and Letters, 1996The size distributions of ( CsI )n Cs +, [Formula: see text], and [Formula: see text] (M: alkali metal, j=1, 2, 3, 4, 5) clusters were obtained using secondary-ion mass spectrometry. The sizes of stable neutral clusters ( CsI )n and ( Hg )n clusters were determined from the mass spectra of cluster ions ( CsI )n Cs + and ( Hg )nM+. The magic numbers of

Investigation of hydrogen sensitivity of SIMS method
Surface and Interface Analysis, 1992Abstract Generally, papers in which hydrogen detection by the SIMS method is described do not touch upon the sensitivity and background level of hydrogen during the SIMS analysis. Problems connected with the detection and sensitivity of hydrogen in our SIMS equipment are discussed in this paper.
