在未煅烧的氧化物样品的熔融过程中，可能会损失不同质量的挥发性成分，对应于烧失量（LOI）。另一方面，部分还原的样品，如铁矿石的烧结物，可能含有一种或多种与空气中着火增益（GOI）有关的处于各种氧化状态的元素。这两种现象都影响从熔融样品获得的分析物X射线荧光强度。
充分的解释沿着与一个严格的数学处理所提出的方法，已证明其实用价值，在过去的十年。它基于德容-诺里什方程，其中质量差LOI-GOI被视为具有指定原子序数零的一个元素。参考了实际结果。
During fusion of uncalcined oxide samples there may be a loss of a variable mass of volatile constituents, corresponding with the loss on ignition (LOI). On the other hand, partially reduced samples, such as sinters of iron ores, may contain one or more elements in various states of oxidation related to the gain on ignition in air (GOI). Both phenomena influence the analyte X-ray fluorescence intensities obtained from the fused sample.
Full explanations are given along with a rigorous mathematical treatment for a proposed method that has demonstrated its practical value in the past decade. It is based on the de Jongh–Norrish equations in which the mass difference LOI–GOI is treated as one element with the assigned atomic number zero. References are made to practical results.
