What are Vo and Vt in Empower or Breeze GPC software? - WKB6155

Article number: 6155

ENVIRONMENT

  • Empower
  • Empower 2
  • Empower 3
  • Breeze
  • Breeze 2

ANSWER

Vo is the exclusion volume of the set of columns in a GPCV system. Vt is the total retention volume of the set of columns in a GPCV system. You can use both Vo and Vt to extend the valid range of a calibration curve.

ADDITIONAL INFORMATION

As mentioned above, both Vo and Vt can be used to extend the range of a calibration curve. For this reason, they should be measured, and those values used. Artificially creating Vo or Vt values can cause a calibration curve to lose accuracy.
