作者在附有LinK公司860系列Ⅱ能谱仪的JXA—840扫描微分析仪(Scanniny Microanalyger)上,以某些无机盐为试料,用比例法(或称Cliff-Lorimer法),求得比例常数K_B~A,并以K_B~A值作为效率因子(Efficieucy Factor)输入该能谱仪的半定量分析程序中,经某些已知组成的样品验证,证明输入效率因子后,可以得到接近全定量分析的结果,偏差在±1.5％以下(参见附表),满足了某些无机化合物组成分析的要求。显然,偏差是由于所用样品为本体厚样品,又未经ZAF校正所致。使用效率因子时的实验条件必须与求此因子时完全相同。这些条件包括加速电压、背底扣除等。本文着重介绍了背底扣除不同对效率因子值的影响。该方法不需要标准样品,束流的波动对分析结果的影响可
On a JXA-840 Scanniny Microanalyzer equipped with a LinK Company 860 Series II energy dispersive spectrometer, using some of the inorganic salts as a sample, the ratio (or Cliff-Lorimer method) was used to determine the ratio Constant K_B ~ A, and K_B ~ A value as the efficiency factor (Efficieucy Factor) input to the spectrometer semi-quantitative analysis program, the sample validation of some known composition to prove that the input efficiency factor, you can get close to the whole Quantitative analysis of the results, the deviation of ± 1.5% or less (see table), to meet the composition of some inorganic compounds required. Obviously, the deviation is due to the sample used is a bulk sample, without the ZAF correction. The experimental conditions for using the efficiency factor must be exactly the same as for this factor. These conditions include acceleration voltage, background subtraction and so on. This article highlights the different effects of back-subtraction on efficiency factor values. The method does not require a standard sample and the influence of the beam fluctuations on the analysis results can be
