Originally constructed for and installed on a French SAFIRE research aircraft, a ruggedized and specially modified IONICON High-Sensitivity PTR-MS is now on a mission in the Atlantic Ocean. A team of French & German scientists* took the PTR-MS to the sea for the TRANSSIZ campaign aboard the icebreaker R/V Polarstern.

The scientists’ job is to detect trace gases dissolved in water with the help of the PTR-MS and a custom built “On Line Water Extractor Device” (OLWIED).

OLWIED coupled to a PTR-MS is a simple and robust system for on line and high frequency surface sea water analysis. The PTR-MS’ target VOCs are dimethylsulfide, isoprene, acetone, acetaldehyde, acetonitrile, benzene, toluene, xylenes in this study.
