針對我國當(dang)前(qian)地表水(shui)(shui)、飲用水(shui)(shui)源揮發性有機物（VOCs）在(zai)線(xian)監(jian)(jian)測需(xu)求，聚光科技自主(zhu)研(yan)發了VOC-3000 水(shui)(shui)中(zhong)揮發性有機物在(zai)線(xian)監(jian)(jian)測系(xi)統(tong)(tong)。VOC-3000 水(shui)(shui)中(zhong)揮發性有機物在(zai)線(xian)監(jian)(jian)測系(xi)統(tong)(tong)集(ji)自動進(jin)樣(yang)、吹掃、富集(ji)、解(jie)(jie)吸、色譜分(fen)離(li)和數據(ju)處理于一體，可無人監(jian)(jian)守下連續運行(xing)(xing)，準確測量水(shui)(shui)中(zhong)VOCs濃(nong)度(du)，實時遠程傳輸(shu)測量結果，實現(xian)水(shui)(shui)體VOCs污染程度(du)的監(jian)(jian)測與預警。 系(xi)統(tong)(tong)原理 系(xi)統(tong)(tong)將水(shui)(shui)樣(yang)采集(ji)并加熱送入吹掃裝置(zhi)內，然后(hou)向吹掃罐中(zhong)通(tong)入惰性氣(qi)體，將待測水(shui)(shui)樣(yang)中(zhong)VOCs組(zu)(zu)分(fen)吹出，通(tong)過除水(shui)(shui)裝置(zhi)去除吹脫混合(he)氣(qi)中(zhong)的水(shui)(shui)分(fen)，再(zai)將除水(shui)(shui)后(hou)的VOCs組(zu)(zu)分(fen)在(zai)捕集(ji)阱中(zhong)進(jin)行(xing)(xing)富集(ji)，最后(hou)啟動加熱解(jie)(jie)吸，通(tong)過載氣(qi)將解(jie)(jie)吸后(hou)的VOCs組(zu)(zu)分(fen)帶(dai)入色譜進(jin)行(xing)(xing)分(fen)離(li)分(fen)析，獲得各組(zu)(zu)分(fen)濃(nong)度(du)。
