## Abstract A group of five neurotransmitters with different properties was analyzed using atmospheric pressure photoionization (APPI) and atmospheric pressure chemical ionization‐mass spectrometry (APCI‐MS). The sensitivity of the techniques for the analytes was tested in six solvents and in posit
