actions of packing bed for two capillary columns of different diameters,
al 750 (bottom image) and b) 30-μm-i.d. Both columns are packed with the
same stationary phase, spherical particles with 1-um diameter.
A) When the columns were prepared, the figure shows that the column with
the larger diameter has more packing irregularities. Explain this observation.
B) Predict what affect this should have on band broadening and discuss your
prediction using the van Deemter terms.
C) Does this figure support your explanations in application question 33?
Explain why or why not and make any changes in your answers in light of
this figure.
