叙述了一种定量分析岩石中微量元素的火花源质谱法。大约10～25毫克绝缘粉末样品直接压在T型电极上。在选定的分析条件下进行单曝光摄谱。用AGV—1做标准样品,计算相对灵敏度因子。此方法可分析24个元素。相对标准偏差为±20％。做了地幔和月岩等样品分析。
A method for quantitative analysis of trace elements in rock by spark source mass spectrometry is described. Approximately 10-25 mg of insulating powder sample is pressed directly against the T-electrode. Single shot exposure was performed under the selected assay conditions. Using AGV-1 as a standard sample, calculate the relative sensitivity factor. This method can analyze 24 elements. The relative standard deviation is ± 20%. Mantle and moon rock samples were analyzed.
