Easy G-SIMS

EasyGSIMS is a simple Excel spreadsheet allowing simple interpretation of SIMS data through analysis using the GSIMS method. Just take two sets of spectra at low and high fragmentation conditions, input peak intensities into the spreadsheet and obtain simple GSIMS spectra relating directly to the parent molecules.

SIMS Spectrum

G-SIMS is a novel method of obtaining spectra of characteristic peaks from SSIMS. An example of the simplification obtainable with this method is shown here for poly(carbonate).

EasyGSIMS

EasyGSIMS is a simple Excel spreadsheet enabling quick interpretation of your GSIMS data. All that is needed to input into EasyGSIMS is a set of three or more spectra at both low fragmentation conditions, e.g. Cs+, Bi+ or low energy bombardment, and high fragmentation conditions, e.g. Ar+, Mn+ or high energy bombardment. These spectra need to be in the form of a set of mass positions and corresponding peak intensities. Use all the peaks in the spectra for best results. Full instructions, on both taking the data and how to use EasyGSIMS, are given on sheet 2 of the spreadsheet, it is recommended that you read these before taking any data.

The file easygsimsv1.zip contains the EasyGSIMS Excel spreadsheet, example data for poly(carbonate), and a completed example spreadsheet for this data. Please see 'readme.txt' for important information regarding the spreadsheet.

Please note that EasyGSIMS will not work without first having the Solver and Analysis ToolPaks installed in Excel. More details and instructions for installation are given in sheet 2 of the spreadsheet.
