Chapter 26: Q12P (page 747)

(a) State the purpose of the separator and suppressor in suppressed ion chromatography. For cation chromatography, why is the suppressor an anion-exchange membrane?

Short Answer

Expert verified

The solution to the above questions are:

  1. The suppressed ion chromatography os suitable for anion analysis.
  2. For cation chromatography, the suppressor replaces anions from eluent.

Step by step solution

01

Explanation of suppressed ion chromatography being the suitable for anion analysis:

  • The suppressor causes the reduction in the conductivity of the eluent by an exchange in the sample counter ions and eluent with ions derived by a suppressor.
  • It changes cations to hydrogen ions with higher conductivity鈫�H2O
  • It neutralizes the eluent
  • Ions are separated with ion exchange process via separator column.
02

Step2:For cation Chromatography:

In this case the suppressor is an anion 鈥� exchange membrane because the suppressor replaces anions from eluent with hydroxyl ions via anion-exchange membrane

State three different methods to reduce electroosmotic flow. Why does the direction of electroosmotic flow change when a silica capillary is washed with a cationic surfactant?

Explain how neutral molecules can be separated by micellar electrokinetic chromatography. Why is this a form of chromatography? Why are micelles called a pseudostationary phase?

Material balance. If you intend to measure all the anions and cations in an unknown, one sanity check on your results is that the total positive charge should equal the total negative charge. The table lists concentrations of anions and cations measured in pond water in an undergraduate experiment and expressed in mg/mL.

Find the total concentration of negative and positive charge (mol/L) to assess the quality of the analysis. What do you conclude about this analysis?
