Article number: 68830

ENVIRONMENT

  • AccQ•Tag Ultra
  • Amino Acid Analysis

ANSWER

  1. Double check your pH. For AccQ•Tag to work properly, you need to have your samples within the pH range of 8.2 to 10.
  2. Vortex, or mix the sample immediately after adding the derivatization reagent, any delay in time can cause an incomplete derivatization reaction, or lower area counts.
