Figure 4. Column efficiency (N) vs retention factor (k') for 22
nonionizable solutes on FMS (red), PGC (black), and COZ (green). 3000
Eluent compositions (acetonitrile/water, A/W) were adjusted to obtain
k' less than 15, which was achieved for most solutes as follows: FMS
(30/70 A/W), PGC (60/40), COZ (80/20). Slightly different
compositions were used for the most highly retained solutes. All
columns were 50 mm × 4.6 mm id and packed with 5 um particles,
except for COZ, which was packed with 3 um particles. All other
chromatographic conditions were constant: column length 5 cm,
column j.§. 4.6 mm, flow rate 2 mL/min, column temperature 40 °C,
and injection volume 0.5 μL

- 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.
