針對我國當前地表水(shui)(shui)、飲用水(shui)(shui)源揮(hui)(hui)發(fa)性(xing)(xing)(xing)有機物（VOCs）在線(xian)監(jian)(jian)(jian)測需求，聚(ju)光科(ke)技自主研發(fa)了(le)VOC-3000 水(shui)(shui)中(zhong)(zhong)(zhong)揮(hui)(hui)發(fa)性(xing)(xing)(xing)有機物在線(xian)監(jian)(jian)(jian)測系統(tong)(tong)。VOC-3000 水(shui)(shui)中(zhong)(zhong)(zhong)揮(hui)(hui)發(fa)性(xing)(xing)(xing)有機物在線(xian)監(jian)(jian)(jian)測系統(tong)(tong)集(ji)自動(dong)進樣(yang)、吹掃(sao)(sao)、富集(ji)、解吸(xi)、色(se)(se)譜分(fen)離和數據處理(li)于(yu)一體(ti)(ti)，可(ke)無(wu)人監(jian)(jian)(jian)守(shou)下連續(xu)運行(xing)(xing)，準(zhun)確測量水(shui)(shui)中(zhong)(zhong)(zhong)VOCs濃(nong)度(du)，實時遠程傳輸(shu)測量結果，實現水(shui)(shui)體(ti)(ti)VOCs污(wu)染程度(du)的監(jian)(jian)(jian)測與預警。 系統(tong)(tong)原理(li) 系統(tong)(tong)將(jiang)水(shui)(shui)樣(yang)采集(ji)并加熱(re)送入吹掃(sao)(sao)裝置內，然后(hou)向吹掃(sao)(sao)罐中(zhong)(zhong)(zhong)通入惰性(xing)(xing)(xing)氣(qi)體(ti)(ti)，將(jiang)待(dai)測水(shui)(shui)樣(yang)中(zhong)(zhong)(zhong)VOCs組分(fen)吹出，通過(guo)除水(shui)(shui)裝置去除吹脫混合氣(qi)中(zhong)(zhong)(zhong)的水(shui)(shui)分(fen)，再將(jiang)除水(shui)(shui)后(hou)的VOCs組分(fen)在捕集(ji)阱中(zhong)(zhong)(zhong)進行(xing)(xing)富集(ji)，最后(hou)啟動(dong)加熱(re)解吸(xi)，通過(guo)載氣(qi)將(jiang)解吸(xi)后(hou)的VOCs組分(fen)帶入色(se)(se)譜進行(xing)(xing)分(fen)離分(fen)析，獲得各(ge)組分(fen)濃(nong)度(du)。
