Just added to AlphaDelta, the theoretical sulfur isotope fractions for the sulfide-sulphate system from:
Eldridge DL, Guo W, Farquhar J (2016) Theoretical estimates of equilibrium sulfur isotope effects in aqueous sulfur systems: Highlighting the role of isomers in the sulfite and sulfoxylate systems. Geochimica et Cosmochimica Acta 195:171-200. doi: http://dx.doi.org/10.1016/j.gca.2016.09.021.

Redirecting

AlphaDelta updated today with a new equation:
Saccocia PJ, Seewald JS, Shanks Iii WC (2015) Oxygen isotope fractionation in the portlandite–water and brucite–water systems from 125 to 450 °C, 50 MPa. Geochimica et Cosmochimica Acta 169: 137-151.

AlphaDelta a une nouvelle adresse web!

Nouveauté: le calcul de 1000 ln "alpha" produit un graphique en fonction de 10^6/T^2.

AlphaDelta AlphaDelta offre deux possibilités de calcul : 1) calcul du fractionnement isotopique (1000 ln α) à une température donnée (nouveau-avec graphique);2) calcul de la température d'équilibre isotopique pour une différence de composition (Δ). 1) compute the isotope fractionation (1000 ln α) for a given…

A new version of AlphaDelta is now available on the iTunes Store.

What is NEW!

1) A function to export a .csv formatted file of your last computations and send it by email.
2) A history of your computations, can be managed, deleted.
3) Cool: the new version optimized for the iPad! check it now!
