Urine Expert is a new product from the authors of JESS.

Urine Expert computes the solubilities of key minerals in urine, including common stone-forming minerals apatite, brushite, octacalcium phosphate, whewellite, and weddellite and rarer minerals containing magnesium, ammonium, phosphate, sulfate and urate.

Urine Expert features a convenient and easy-to-use graphical interface (Figure 1) offering immediate practical results (Figure 2) from a powerful chemical speciation model.

Saturation indices (as lg(SI)) are reported for over 40 minerals.

Urine Expert is made available to non-commercial users for a nominal fee. Contact Peter May for more information or to obtain access.
