HMA-2000系列重金屬在(zai)(zai)線(xian)分析儀采(cai)用(yong)陽極(ji)(ji)溶(rong)(rong)出(chu)(chu)(chu)伏安法檢(jian)測(ce)(ce)原理(li)。經預處理(li)的(de)(de)水樣在(zai)(zai)高(gao)溫高(gao)壓(ya)消解(jie)后，與電(dian)解(jie)液在(zai)(zai)檢(jian)測(ce)(ce)池(chi)內混(hun)合(he)，然后在(zai)(zai)電(dian)極(ji)(ji)上(shang)(shang)施(shi)加一還原電(dian)勢將(jiang)混(hun)合(he)液中(zhong)的(de)(de)待測(ce)(ce)金屬離(li)子富集在(zai)(zai)工(gong)作電(dian)極(ji)(ji)上(shang)(shang)，再按階(jie)梯(ti)脈沖方式持續改變(bian)外加電(dian)勢，使富集在(zai)(zai)工(gong)作電(dian)極(ji)(ji)上(shang)(shang)的(de)(de)金屬元素溶(rong)(rong)出(chu)(chu)(chu)，并檢(jian)測(ce)(ce)溶(rong)(rong)出(chu)(chu)(chu)時(shi)的(de)(de)電(dian)流信號強度，根(gen)據溶(rong)(rong)出(chu)(chu)(chu)電(dian)流信號峰強度換算得(de)到被測(ce)(ce)組(zu)分的(de)(de)濃(nong)度。
HMA-2000系列重金(jin)(jin)屬在(zai)線分(fen)析儀采用陽(yang)極(ji)(ji)溶(rong)出(chu)伏安法(fa)檢測(ce)原理(li)。經預處(chu)理(li)的水樣在(zai)高溫高壓消解后，與電(dian)(dian)(dian)解液在(zai)檢測(ce)池(chi)內混合，然后在(zai)電(dian)(dian)(dian)極(ji)(ji)上施加(jia)一還原電(dian)(dian)(dian)勢(shi)將混合液中的待測(ce)金(jin)(jin)屬離子(zi)富集在(zai)工作(zuo)電(dian)(dian)(dian)極(ji)(ji)上，再(zai)按階梯脈沖方式持續(xu)改變外(wai)加(jia)電(dian)(dian)(dian)勢(shi)，使富集在(zai)工作(zuo)電(dian)(dian)(dian)極(ji)(ji)上的金(jin)(jin)屬元素溶(rong)出(chu)，并(bing)檢測(ce)溶(rong)出(chu)時的電(dian)(dian)(dian)流信(xin)號強度(du)(du)，根(gen)據(ju)溶(rong)出(chu)電(dian)(dian)(dian)流信(xin)號峰強度(du)(du)換算得到(dao)被測(ce)組分(fen)的濃(nong)度(du)(du)。
