Capillary liquid chromatography/mass spectrometry (LC/MS) is usually performed using electrospray ionization. Atmospheric pressure chemical ionization (APCI) has not been used since the flow rates involved (1-10 µL/min) are too low to effect ionization with a standard APCI source. Using a 320 µm ؋ 1
