CasaXPS Training (2 days)
CasaXPS was written by Neal Fairley for those who routinely work with XPS/ESCA spectra. CasaXPS offers user-friendly data processing for anyone with a PC running Microsoft Windows 95 or later. CasaXPS contains file converters for converting manufacturers’ file formats into the ISO standard data format, so data from different instruments can be processed using the same versatile software. Spectra from different datasets or different instruments can also be combined into a new file for better comparison. The results of data processing, such as curve fitting and quantitative analysis, are tabulated and made available in a convenient format for use in Microsoft Word, Excel or similar products. Data displays can also be copied with different aspect ratios for use in Microsoft PowerPoint, Word or similar products.
The course will include an overview of the features in CasaXPS, converting data in different file formats (such as from Kratos, Physical Electronics, Surface Science Instruments, and Thermo Fisher Scientific [formerly VG]) into the ISO standard format, different display modes, different peak identification and labeling methods, different background subtraction methods (linear, Shirley, Tougaard,…), peak areas, sensitivity factors and their linked databases, quantitative analysis using default transitions and user-selected transitions, quantitative analysis when peaks from different elements overlap, adding and subtracting spectra, curve fitting, selection of lineshapes and backgrounds, curve fitting using reference spectra, combining curve fit data into quantitative analysis tables, correcting the energy scale for sample charging, propagating processed data to other data, depth profile data, least squares fitting, annotation relative to peaks or to the display box, spectrum zoom, inserting additional spectra within a window, copying spectra into reports, changing aspect ratios, changing fonts, changing line colors, customizing CasaXPS, and creating and saving versions with special databases. The course will not include processing of images or maps.
This course is taught in a hands-on environment, so attendees can learn how to use the many features of this powerful software program. Attendees are encouraged to bring their own laptop and will be provided with a demonstration copy of CasaXPS to keep, data to process, and electronic copies of “An Introduction to XPS and AES” by Neal Fairley, and a user manual.
