environmental survey vehicle and its high-altitude air sampling technology on the outlying islands of Penghu County.
EPA Environmental Analysis Laboratory Acting Director Yen Chun-lan (顏春蘭) said the vehicle, donated by Delta Electronics last year, uses a soft chemical ionization proton transfer reaction time-of-flight spectrometer, which can monitor more than 300 gaseous pollutants that have the ability to bind with oxonium ions using.
