  Headspace vials often come in larger volumes than the 2-mL vials used in many liquid sampling systems. Common offerings are 10 mL and 20 mL capacities,etc. Larger vials accommodate larger sample volume and/or a larger headspace above that sample. Because headspace works best for volatile compounds, using quality vials and caps to form a tight seal is critical to a successful analysis.
