Headspace techniques for VOC analysis. Within a sample vial the unoccupied area above the sample is commonly referred to as the head space. Using static headspace, sealed vials containing sample are gently heated to drive VOC compounds out of the sample matrix into equilibrium with the gas phase.

Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk.
2 days ago · Thirty milliliters of the solution was put in a 40 mL vial. All vials were placed in an incubator at 25 °C in the dark. After 10 days, The headspace of the vials (100 μL) was extracted using a gas-tight syringe. The 0.8 mL of water in the vials was extracted with 0.8 mL of dichloromethane (Bonifacio et al., 2017).
