Recent advancements in liquid chromatography include the development of ultrahigh pressure liquid
chromatography (UHPLC) and an increased use of capillary columns that had previously only been used
with gas chromatography. Both of these advances have made the development of portable LC systems
possible. For example, Axcend Corp. makes a portable system that uses a capillary column with an
internal diameter of 150-μm-that is packed with 1.7-um stationary phase particles. 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. Explain one disadvantage of capillary columns.
b) Explain how the use of smaller stationary phase particles can improve the resolution of a separation.
Include any relevant equations that support your explanation.
c) A scientist at Rowan University is using
the Axcend LC to conduct analyses of F…
This paper describes the use of fullerene molecules, also known as buckyballs, as a stationary phase for
liquid chromatography. The performance of the fullerene-modified stationary phase (FMS) is compared to
that of a more common C18 stationary phase and to two other carbon-based stationary phases, PGC and
COZ.

A 3D-printed GC column (shown below) was created for use with "micro" gas chromatography
applications. To prove its utility, it was used to separate a mixture of alkanes (C9-C18, C22, C24). For the
separation shown below, the column temperature was ramped from 40 °C to 250 °C at a rate of 30 °C per
minute.

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.
