在高压火花条件下,采用大电感对电极激发,可以提高锌谱线强度。选用Al3059.9A作为基体线时,锌的分析结果准确度较好。本条件同时可用于镁、铁、铜、锰等元素的分析。试验部分 1 标准样品采用ZL101铸铝合金,锌的含量如:1# 0.124;2# 0.195;3# 0.225;4# 0.39%。 2 电极形转的选择对半球形对电极;上电极为纯铝半球形,下电极为试样平面和上电极为圆锥形纯碳电极,下电极为试样平面等电极组合进行比较。试验结果证明,半球形
In the high-pressure spark conditions, the use of large inductors on the electrode excitation, zinc line can increase the intensity. When using Al3059.9A as the matrix line, the accuracy of zinc analysis is good. The conditions at the same time can be used for magnesium, iron, copper, manganese and other elements of the analysis. Test part 1 standard sample using ZL101 cast aluminum alloy, zinc content such as: 1 # 0.124; 2 # 0.195; 3 # 0.225; 4 # 0.39%. 2 Electrode rotation Select the hemispherical counter electrode; the upper electrode is pure aluminum hemispherical, the lower electrode is the sample plane and the upper electrode is a conical pure carbon electrode, the lower electrode is a sample plane electrode combination for comparison. Experimental results show that hemispherical
