Sample volume at which a defined amount of an analyte pumped continuously through an extraction device will begin to be eluted.
Typical breakthrough curve indicating the breakthrough volume \(V_{\rm{B}}\) and the sample volume corresponding to the saturation capacity of the sorbent \(V_{\rm{C}}\) (\(V_{\rm{R}}\) corresponds to the chromatographic elution volume and \(\upsigma\!_{\rm{v}}\) the standard deviation of the derivative of the curve).
Notes:
- The breakthrough volume, \(V_{\rm{B}}\), for a particular compound and sampling device is determined by its breakthrough curve (see figure).
- Defined amounts are usually given as a volume fraction of the sample volume (e.g. \(\pu{1\%}\), \(\pu{5\%}\) or \(\pu{10\%}\), etc.).
