Answer Posted / kanakadurga
Packed columns have higher sample capacity than capillary
column.
Improvements in detector sensitivity have also reduced the
need for large samples.For almost all other samples,
capillaries provide much better efficiency (narrow peaks)
which leads to greatly improved peak separation. Capillary
columns are highly sensitive and efficient. these are two
types WCOT and PLOT.
Yes these are depends on Sample Load. Very Low quanity of
samples are enough for the analysis.
