A vial-in-vial method is used, in which the volatile agent is placed in a small inner vial, and the inner vial is capped with a layer of fabric or film to be tested. The agent permeates from the inner vial into an outer headspace vial. The instrument samples the vapor in the outer vial by sampling it and injecting it into the GC for analysis.
In addition to the features on standard 2 mL vials, SureStop vials also have a patented definite stop point (alignment ring) in the design of the vial finish. This prevents the vial from being an optimal seal which eliminates under- and over-sealing by the cap/closure, and user-to-user variance.

Jun 11, 2020 · Although the data certainly appear to fall along a straight line, the actual calibration curve is not intuitively obvious. The process of determining the best equation for the calibration curve is called linear regression. Figure 5.4.1 : Normal calibration curve data for the hypothetical multiple-point external standardization in Table 5.4.1 .
