This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

This lab includes the complete titration procedure used to investigate how well a buffer resists changes in pH. Prepare a buffer solution by accurately calculating and measuring the required amounts ...

In this study, stimulus-sensitive gel particles with DNA–dye complexes were prepared. This composite has potential use in optical micro-sensors because it can change its dye concentration in response ...

in 1909 S.P.L Sorenson, a Danish biochemist devised a scale known as pH to represents the H + ion concentration of an aqueous solution. The pH value of any solution is a number that simply represents ...

Recently, the trend of outsourcing buffer manufacturing system has been adopted by pharmaceutical companies as it reduces the cost of buffer formulation, eliminates space and temperature maintenance ...
