Data for: Low analytical totals in EPMA of hydrous silicate glass due to sub-surface charging: Obtaining accurate volatiles by difference

Data for "Low analytical totals in EPMA of hydrous silicate glass due to sub-surface charging: Obtaining accurate volatiles by difference". Example_calibration.xlsx = data and calculation using data from Lesne et al. (2011) (Journal of Petrology) to show an example of the VBD calibration. Literature_data.xlsx = all literature data collated to investigate the accuracy of VBD compared to direct techniques used to analyse volatiles in silicate glass. Win_X-ray_results.xlsx = summary of results from Win X-ray PRZ_curves = example of PRZ curves produced from Win X-ray Rest of the files = input and output files from Win X-ray simulations
