6. The solution of claim 1 , wherein the pH is greater than 8.
7. The solution of claim 1 , wherein the pH is greater than 9.
8. The solution of claim 1 further comprising a component selected from the group consisting of osmotic agents, electrolytes and combinations thereof.
9. The solution of claim 8 , wherein the osmotic agent is selected from the group consisting of glucose, glucose polymers, glucose polymer derivatives, cyclodextrins, modified starch, hydroxyethyl starch, polyols, fructose, amino acids, peptides, proteins, amino sugars, glycerol, N-acetyl glucosamine (NAG) and combinations thereof.
10. The solution of claim 8 , wherein the buffer further comprises a component selected from the group consisting of lactate, pyruvate, acetate, citrate, tris, amino acids, peptides, an intermediate of the KREBS cycle and combinations thereof.
11. The solution of claim 1 further comprising at least two parts housed separately and the pyrophosphate and the bicarbonate buffer are present with at least one of the parts and sterilized with said part.
12. The solution of claim 11 , wherein the part comprising the pyrophosphate and the bicarbonate buffer has a pH greater than 8.
13. The solution of claim 11 , wherein the part comprising the pyrophosphate and the bicarbonate buffer has a pH greater than 9.
14. The solution of claim 11 , wherein electrolytes are balanced between the first part and the second part.
15. The solution of claim 1 , wherein the solution is a dialysis solution.
16. A heat sterilized dialysis product comprising:
a first dialysis part comprising a dialysis component selected from the group consisting of osmotic agents, electrolytes and combinations thereof; and
a second dialysis part comprising pyrophosphate, bicarbonate and a pH greater than 7, wherein the bicarbonate and the pH greater than 7 heat stabilize the pyrophosphate.
17. The dialysis product of claim 16 , wherein the pyrophosphate ranges from about 0.1 μM to about 1000 μM.
