Question
Chapter 10, Problem 44E
Interpretation Introduction
Interpretation:
Explanation for why water forms into beads on a waxed car finish has to be given.
Concept introduction:
Water is a typical polar molecule. It has strong cohesive forces among its molecules through intermolecular hydrogen bonding. It can have adhesive forces with other polar molecules in solid form like glass. With non-polar molecules, water has no adhesive force.

Both of these advances have made the development of portable LC systems possible.

In contrast, a traditional LC column has a 4.6 mm internal diameter and utilizes 5-um stationary phase particles. a) Explain one advantage that is afforded by the use of a capillary column in liquid chromatographic separation.

- Heparin is used as an anti-coagulant. A risk of heparin use is thrombocytopenia, or low platelet count. This risk is minimized with the use of low molecular weight heparins (LMWH), therefore it is desirable to separate LMWH from higher molecular weight heparins. The method of choice to do this is molecular exclusion chromatography. Below is a chromatogram from a molecular exclusion chromatographic run. Peaks ranging from A to J are clearly distinguishable. The heparin mixture that was analyzed had anywhere from 6 to 30 repeat units of monomer (where the heparin with 30 repeat units would be roughly five times the size of the heparin with six repeat units). a. Which letter most likely represents the peak with 6 repeat units given these heparin polymers were separated with molecular exclusion chromatography? b.
