    1.1 本型氫化物發(fā)生器屬流動(dòng)注射型, 必須與原子吸收分光光度計(jì)主機(jī)配合使用, 用氫化物原子吸收法測(cè)定試樣中痕量砷、硒、銻、鉍、鉛、 錫、 碲、鍺和冷原子吸收法測(cè)定汞。

    1.2 工作情況:用載氣壓力作為自動(dòng)化能源, 按下啟動(dòng)鍵, 自動(dòng)定量吸入3 種溶液(硼氫化鉀、試樣、載液), 吸滿后發(fā)出讀數(shù)信號(hào), 載帶試樣溶液的載液和硼氫化鉀溶液開始穩(wěn)流流動(dòng), 會(huì)合后發(fā)生反應(yīng),生成物被載氣帶入氣液分離管, 混合氣進(jìn)入電熱石英吸收管原子化器,廢液自動(dòng)排出,主機(jī)用峰高法讀數(shù),也可用峰面積法讀數(shù)。
