Solution A (0.1 M) was prepared by dissolving 1.98 g of Na2HPO4·2H2O p.a. (Merck KGaA, Darmstadt, Germany) in 500 mL of demineralised water (Brataco, Semarang, Indonesia), while Solution B (0.1 M) was prepared by dissolving 1.56 g of NaH2PO4·2H2O p.a. (Merck KGaA, Darmstadt, Germany) in 500 mL of demineralised water (Brataco, Semarang, Indonesia). Solutions A (80.2 mL) and B (19.8 mL) were then homogenised before the pH was adjusted to 7.4 using diluted 0.1 M hydrochloric acid (HCl) p.a. or 0.1 M sodium hydroxide (NaOH) p.a.

Solution C (0.05 M) was prepared by dissolving 7.5 g of Na2HPO4·2H2O p.a. (Merck KGaA, Darmstadt, Germany) in 500 mL of demineralised water (Brataco, Semarang, Indonesia), while Solution D (0.05 M) was prepared by dissolving 3.9 g of NaH2PO4·2H2O p.a. (Merck KGaA, Darmstadt, Germany) in 500 mL of demineralised water (Brataco, Semarang, Indonesia). The SIF was prepared by homogenising Solutions C (40.5 mL) and D (9.5 mL) and then diluting the mixture to 100 mL before adjusting the pH to 7.4 using diluted 0.1 M HCl p.a. or 0.1 M NaOH p.a.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
