Compounds

  1. 4-Hydroxy-3-methoxymetmamphetamine (HMMA). 
  2. 3,4-Methylenedioxyamphetamine (MDA) 
  3. MDMA-D5 (ISTD) 
  4. 3,4-Methylenedioxymethamphetamine (MDMA)

Analysis at pH 9 allows good peak shape and maximum retention for basic compounds  with no modifiers that can interfere with LC-MS analysis. Do not try this with traditional  silica based columns.
