The phase ratio is affected by vial size and the sample volume. A best practice when optimizing phase ratio is to leave at least 50% of headspace in the vial. Therefore, using a 20-mL vial instead of a 10-mL vial allows a greater volume of sample (Figure 5).
Dec 16, 2019 · Dec. 16th, 2019. When sampling the headspace vial should be pressured, using its pressure to the gas phase part (headspace phase) export of the small glass bottle method called the balance pressure method. As the best device, when the pressure of the separation system is balanced, the headspace phase is directed directly into the column for
