Characterizing the delay volumes: Mixing point to UV detector and Column to UV detector
2 Calculate the final Mixing point to UV detector tubing volume as the sum
of:
• Mixing point to column tubing volume: step 1
• Column to UV detector tubing volume: see “Calculation of delay volume:
Column to UV detector” on page 50
