本法采用硝酸、氢氟酸、高氯酸以及磷酸分解后，在25％的磷酸介质中，锗与硼氢化钾反应氢化物气体，以氩气为载气导入电热石英炉，火焰中与氢基碰撞离解为自由原子，在空心阴极灯光源的激发下产生荧光光谱。以锗的浓度为横坐标，荧光峰高值为纵坐标绘制工作曲线，从而测出试样中锗的浓度。
本法採用硝痠、氫氟痠、高氯痠以及燐痠分解後，在25％的燐痠介質中，鍺與硼氫化鉀反應氫化物氣體，以氬氣為載氣導入電熱石英爐，火燄中與氫基踫撞離解為自由原子，在空心陰極燈光源的激髮下產生熒光光譜。以鍺的濃度為橫坐標，熒光峰高值為縱坐標繪製工作麯線，從而測齣試樣中鍺的濃度。

After decomposed by nitric acid, hydrofluoric acid, perchloric acid, and phosphoric acid , in 25%of the phos-phoric acid medium, germanium reacts with potassium borohydride to produce hydride gases which is imported to electric quartz furnace with argon as carrier gas , collide with hydrogen atoms in flames to dissoved to free atoms,and emit fluores-cence spectrum under the excitation of the hollow cathode light source .High concentration of germanium as abscissa, fluo-rescence peak value as the y-coordinate, working curve are drawn out and the concentration of germanium in the sample are measured.
