HMA-2000系列(lie)重金(jin)屬(shu)(shu)在(zai)(zai)線分(fen)析儀采用陽極溶出伏(fu)安法檢(jian)測(ce)原理。經(jing)預處理的水樣在(zai)(zai)高(gao)溫高(gao)壓消解后，與電(dian)(dian)(dian)(dian)(dian)解液(ye)在(zai)(zai)檢(jian)測(ce)池內混(hun)(hun)合，然(ran)后在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)極上施加一還(huan)原電(dian)(dian)(dian)(dian)(dian)勢將混(hun)(hun)合液(ye)中的待測(ce)金(jin)屬(shu)(shu)離(li)子富集(ji)在(zai)(zai)工(gong)作電(dian)(dian)(dian)(dian)(dian)極上，再(zai)按階梯脈(mo)沖方式(shi)持續(xu)改變外加電(dian)(dian)(dian)(dian)(dian)勢，使(shi)富集(ji)在(zai)(zai)工(gong)作電(dian)(dian)(dian)(dian)(dian)極上的金(jin)屬(shu)(shu)元素溶出，并(bing)檢(jian)測(ce)溶出時的電(dian)(dian)(dian)(dian)(dian)流信(xin)號(hao)強度，根據溶出電(dian)(dian)(dian)(dian)(dian)流信(xin)號(hao)峰強度換算得到被(bei)測(ce)組分(fen)的濃度。
HMA-2000系列重金(jin)(jin)屬(shu)在線分(fen)析儀采(cai)用陽極(ji)(ji)溶(rong)出伏安法檢測(ce)(ce)原理。經預處理的(de)水樣在高溫高壓消解后，與(yu)電解液在檢測(ce)(ce)池(chi)內混(hun)(hun)合，然后在電極(ji)(ji)上施加一(yi)還(huan)原電勢將混(hun)(hun)合液中的(de)待測(ce)(ce)金(jin)(jin)屬(shu)離子(zi)富集在工作電極(ji)(ji)上，再按階梯脈(mo)沖(chong)方(fang)式持續改變外加電勢，使富集在工作電極(ji)(ji)上的(de)金(jin)(jin)屬(shu)元素溶(rong)出，并檢測(ce)(ce)溶(rong)出時的(de)電流(liu)信號(hao)強度(du)，根據溶(rong)出電流(liu)信號(hao)峰強度(du)換算得(de)到被(bei)測(ce)(ce)組(zu)分(fen)的(de)濃度(du)。
