We present a technique that utilises a segmented
flow coil equilibrator coupled to a proton-transferreaction
mass spectrometer to measure a broad range of dissolved
volatile organic compounds. Thanks to its relatively
large surface area for gas exchange, small internal volume,
and smooth headspace–water separation, the equilibrator is
highly efficient for gas exchange and has a fast response time
(under 1 min). The system allows for both continuous and
discrete measurements of volatile organic compounds in seawater
due to its low sample water flow (100 cm3 min
