论文摘要
在这项工作中,我们研究了TXRF光谱的局限性在技术的有效性上限时,当分析的样品停止为薄膜时。我们已经评估了从临时样品获得的光谱中的非线性效应,这些效应是以预先建立的稀释序列获得的。因此,在高,中和低计数的条件下获得光谱,因此,对非线性效应进行了顺序评估,这是样本量的函数。根据这项工作的结论,应避免死时间,因为一旦获得光谱,其影响是不可预测的和不可逆转的。
In this work we have studied the limitations of the TXRF spectroscopy in the upper limit of validity of the technique, when the analyzed specimen ceases to be a thin film. We have evaluated the non-linear effects in spectra obtained from samples made ad-hoc, which were acquired in a pre-established sequence of dilutions. So, the spectra were obtained in conditions of high, medium and low counts, thus the nonlinear effects were sequentially evaluated, as a function of the sample amount. According to the conclusions of this work, the Dead Time should be avoided since its effects are unpredictable and irreversible once the spectra are obtained.
