Optional Features
The following features can be purchased right in Alph from the Alph Store. The Apple App store will price these in your local currency, which will be displayed with the description on the store page. The price in Canadian and US dollars is displayed below as a guide.
Includes all Alph options and compounds listed below and expands the total compound library to over 5600 compounds. It also Includes VMG's NRTL property package for chemical systems.
VMG's modification of NIST's 1995 and 1997 steam tables. Modifications include calculating multicomponent mixtures, water decantation for hydrocarbon systems and highly accurate solubility of important industrial gases in water such as nitrogen and oxygen.
Add hydrocarbon compounds that are not in the library, by characterizing them with the normal boiling point and optionally liquid density, molecular weight, critical temperature, critical pressure and the acentric factor. Custom Compound Help Page.
