針對我國當前地表水(shui)、飲用水(shui)源揮發(fa)性(xing)有機物（VOCs）在(zai)(zai)線監測需求，聚光(guang)科技自主研發(fa)了VOC-3000 水(shui)中(zhong)(zhong)(zhong)揮發(fa)性(xing)有機物在(zai)(zai)線監測系統(tong)。VOC-3000 水(shui)中(zhong)(zhong)(zhong)揮發(fa)性(xing)有機物在(zai)(zai)線監測系統(tong)集自動進樣(yang)、吹掃(sao)、富集、解(jie)(jie)吸(xi)、色譜(pu)分(fen)(fen)(fen)離和數據處理于一體，可無人(ren)監守下連續運行，準確測量(liang)水(shui)中(zhong)(zhong)(zhong)VOCs濃(nong)(nong)度(du)，實時遠程(cheng)傳輸測量(liang)結果，實現水(shui)體VOCs污染程(cheng)度(du)的監測與預警(jing)。 系統(tong)原理 系統(tong)將(jiang)水(shui)樣(yang)采集并加(jia)熱送入(ru)吹掃(sao)裝(zhuang)置(zhi)內，然后向(xiang)吹掃(sao)罐中(zhong)(zhong)(zhong)通(tong)入(ru)惰性(xing)氣(qi)體，將(jiang)待測水(shui)樣(yang)中(zhong)(zhong)(zhong)VOCs組分(fen)(fen)(fen)吹出，通(tong)過除(chu)水(shui)裝(zhuang)置(zhi)去(qu)除(chu)吹脫混合氣(qi)中(zhong)(zhong)(zhong)的水(shui)分(fen)(fen)(fen)，再將(jiang)除(chu)水(shui)后的VOCs組分(fen)(fen)(fen)在(zai)(zai)捕(bu)集阱中(zhong)(zhong)(zhong)進行富集，最(zui)后啟動加(jia)熱解(jie)(jie)吸(xi)，通(tong)過載氣(qi)將(jiang)解(jie)(jie)吸(xi)后的VOCs組分(fen)(fen)(fen)帶入(ru)色譜(pu)進行分(fen)(fen)(fen)離分(fen)(fen)(fen)析，獲得各組分(fen)(fen)(fen)濃(nong)(nong)度(du)。
