XRFCalc app for iPhone and iPad

Two calculators are included in the XRFCalc app:

1. Elements weight fractions from a formula, e.g.
Fe2(SO4)3*5H2O: total mass = 489.95
Fe=22.8%, S=19.6%,O=55.5%,H=2.1%

2. A table of X-Ray absorption edges and fluorescence line energies is provided.

3. The absorption (photoelectric, coherent (Rayleigh) and incoherent (Compton)) of the specified compound for the specified energy is computed and displayed.
