• The oven controls the temperature of the column.
• In GC, there is the advantage of both interaction of the
analyte with the stationary phase and the boiling point for
separation of compounds.
• The injection is often made at a lower temperature and
the temperature is programmed to elevate.
• Compound elution time and resolution are extremely
dependent on temperature. The higher temperature will
cause the sample to elute faster.
• Oven temperature program rates are range from
0.1°C/min to the maximum temperature heating rate the
GC can provide. A rate of 2-10 °C/min is most common.
