HMA-2000系(xi)列重金(jin)屬(shu)在(zai)線分析儀采(cai)用陽極(ji)(ji)溶(rong)出(chu)伏安(an)法檢(jian)(jian)測(ce)原(yuan)理。經(jing)預處理的水樣在(zai)高溫高壓消解后，與電(dian)(dian)(dian)(dian)解液在(zai)檢(jian)(jian)測(ce)池內混合，然(ran)后在(zai)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)施(shi)加(jia)一還原(yuan)電(dian)(dian)(dian)(dian)勢(shi)將混合液中(zhong)的待測(ce)金(jin)屬(shu)離子富集在(zai)工作電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，再按階梯脈沖(chong)方式持續改變外加(jia)電(dian)(dian)(dian)(dian)勢(shi)，使富集在(zai)工作電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的金(jin)屬(shu)元素溶(rong)出(chu)，并檢(jian)(jian)測(ce)溶(rong)出(chu)時的電(dian)(dian)(dian)(dian)流信號強度，根(gen)據(ju)溶(rong)出(chu)電(dian)(dian)(dian)(dian)流信號峰強度換算得到被測(ce)組分的濃(nong)度。
HMA-2000系列重金屬(shu)(shu)在線分析(xi)儀采用陽極溶(rong)出伏安法(fa)檢測(ce)(ce)原(yuan)理。經預(yu)處理的水樣在高溫高壓消(xiao)解后，與電(dian)解液(ye)在檢測(ce)(ce)池內混合(he)，然后在電(dian)極上施加一還(huan)原(yuan)電(dian)勢將混合(he)液(ye)中的待(dai)測(ce)(ce)金屬(shu)(shu)離子富(fu)集(ji)在工作(zuo)電(dian)極上，再按階梯脈沖方(fang)式持(chi)續改變外加電(dian)勢，使富(fu)集(ji)在工作(zuo)電(dian)極上的金屬(shu)(shu)元素溶(rong)出，并檢測(ce)(ce)溶(rong)出時的電(dian)流信(xin)號(hao)強(qiang)度(du)，根(gen)據(ju)溶(rong)出電(dian)流信(xin)號(hao)峰強(qiang)度(du)換算得(de)到被測(ce)(ce)組分的濃度(du)。
