Given below are two statements:
Statement I: Ion exchange chromatography exploits differences in the sign and magnitude of the net electric charge of proteins at a given pH.
Statement II: In ion exchange chromatography, separation can be optimized by gradually changing the pH and/or salt concentrations of the mobile phase to create pH or salt gradient.
In the light of the above statements, choose the correct answer from the options given below:
1
Both Statement I and Statement II are correct
2
Both Statement I and Statement II are incorrect
3
Statement I is correct but Statement II is incorrect
