a
Gas chromatography/mass spectrometry.
b
The water sample was obtained from a commercial ultrapure laboratory water system that consisted of two ion-exchange stages, ultraviolet light dosing (to photo-oxidize organics), a third ion-exchange stage, and an ultrafiltration membrane; the resistivity of this water was 18.2 MΩ·cm.
c
Gas chromatography/mass spectrometry/infrared spectroscopy.
d
Gas chromatography/quadrupole time-of-flight mass spectroscopy.
