b) Lower concentration of hexane to increase solvent strength

based on someone else answered this for someone else and got 2 dislikes.

Hint: Peak separation can be improved by increasing the retention times.

When an unknown mixture's peaks are too close together and eluted in the range k1-3, what change in the solvent composition would you make in each of the following situations, and why? (a) Reversed phase column using (b) Normal phase column usin 50% tetrahydrofuran/50% water 50% hexane/50% diethyl ether Lower concentration of hexane to lower solvent strength Lower concentration of hexane to increase solvent strength Increase concentration of hexane to lower solvent strength Increase concentration of hexane to increase solvent strength Lower concentration of O O O O tetrahydrofuran to lower solvent strength Lower concentration of tetrahydrofuran to increase solvent strength Increase concentration of tetrahydrofuran to lower solvent strength Increase concentration of tetrahydrofuran to increase solvent strength O

Explanation / Answer

a) Lower concentration of tetrahydrofuran to lower solvent strength

b) Increase concentration of hexane to lower solvent strength
