Getting more from XPS imaging: multivariate analysis for spectromicroscopy
The spherical mirror analyser (SMA) is used to acquire fast XPS images from specimen surfaces with high lateral and energy resolution. Here we review the properties of the SMA including spatial and energy resolution and provide examples of the capabilities of such an imaging analyser. In the last few years the combination of the SMA with a two-dimensional, pulse counting electron detector has a...
متن کاملMultivariate image analysis methods applied to XPS imaging data sets
Recent improvements in imaging photoelectron spectroscopy enhance lateral and vertical characterization of heterogeneous samples at the cost of increasing complexity in the XPS data sets acquired. These imaging data sets require more sophisticated analysis methods than visual inspection if the data are to be interpreted effectively. Multivariate analysis (MVA) methods are increasingly utilized ...
متن کاملXPS MultiQuant: multimodel XPS quantification software
A program for quantitative evaluation of x-ray photoelectron spectra has been developed to serve as a practical tool for surface chemists. The program uses the ‘classic’ approach of quantification and requires as input the integrated intensities of the measured XPS lines. The usual correction methods and factors can be applied and controlled independently. All necessary basic data for calculati...
متن کاملDemystifying imaging laboratory accreditation.
t is self-evident that patients expect high quality of the services they receive. For this reason, procedural-based medical (therapeutic) services have long been subject to some form of quality assessment. In the same vein, it is also appropriate that similar expectations have recently come about for cardiovascular (CV) imaging (diagnostic) services. In this report, we provide the background of...
متن کاملPackage ‘ xps ’
Description The package handles pre-processing, normalization, filtering and analysis of Affymetrix GeneChip expression arrays, including exon arrays (Exon 1.0 ST: core, extended, full probesets), gene arrays (Gene 1.0 ST) and plate arrays on computers with 1 GB RAM only. It is an R wrapper to XPS (eXpression Profiling System), which is based on ROOT, an object-oriented framework developed at C...
