style="text-indent:25px">2檢測方法編輯水質總氮的測定水質總氮的測定方法主要有： 1.堿性過***鉀紫外分光光度法（HJ 636~2012）：現如今，水質監(jiān)測的主要方法，如英國RAIKING，中國銳泉等品牌是主流的在這個標準基礎上優(yōu)化的在線監(jiān)測產品。 2.氣相分子吸收光譜法：該方法主要應用于實驗室。 3.也有采用氨氮、硝酸根、亞硝酸根分別進行測量，然后將結果累加值作為總氮的測量結果。典型應用如德國WTW。在環(huán)境地表水、水質監(jiān)測領域，堿性過***鉀紫外分光光度法以及優(yōu)化方法是當前的主要方法。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

1—獨特的設計，使本產品較之同類產品具有更低故障率、更低維護量、更低的試劑消耗量以及更高的性價比和準確度。 2—利用光電計量管系統(tǒng)克服了蠕動泵流量不穩(wěn)定造成的誤差：增加了一個可視式光電定量裝置，通過液面遮擋光線引起信號的改變，精確實現試劑定量，所以該法克服了軟管磨損降低定量精度的缺點。 3—同時實現了微量試劑的精確定量，**減少了試劑使用量。 4—多向選擇閥，通道靈活多樣，摒棄了昂貴的隔膜電磁閥，**降低了維護量和維護成本。隔膜電磁閥雖然防腐性能很高，但是對試劑清潔度卻有較高的要求，試劑不潔時，經常會出現倒流，并且這類電磁閥具有隨其開閉而使流體被吸入或排出的泵功能，所以對于分析取樣的精度提出了更高的要求，尤其是在所取劑量很少的情況下，帶來的誤差更是嚴重的。本發(fā)明涉及的選擇閥，與目前市場上水質分析儀的電磁閥相比較，具有死體積少，防腐性能高，故障率低，使用壽命長，易維護更換等優(yōu)點。 5—試劑進樣采用蠕動泵負壓吸入方式，保證液體不和泵管接觸，試劑與軟管間存在一個空氣緩沖區(qū)，試劑與軟管沒有直接接觸，所以**降低了軟管的要求并且杜絕了泵管對液體的污染、避免了泵管腐蝕。上海總氮分析儀貨源充足</p><p style="text-indent:25px">上?？偟治鰞x貨源充足</p><p style="text-indent:25px">2019 年
