a) Explain the difference between the split and splitless mode of operation in a GC
injector. Consider properties of the sample in your discussion.
b) Give two reasons why capillary columns are more efficient than packed columns.

a analysed a steel sample during a practical session to establish the concentration of Mn in
sample. The sample was digested in acid and made up to a specific volume in a volumetric
k. You also prepared a 100 ppm working standard solution of Mn2t. After adding the
umes as per Table 2 into a volumetric flask, you diluted to a final volume of 100ml.
cermine the concentration of Mn2+ in the original steel solution
