三种方法，即红外激光烧蚀，辉光放电和火花OES，散装材料的直接固体采样，进行了比较，相对于分析的优点与原子光谱法进行元素分析。研究的基质是铜、压制掺杂铜粉和镁合金。对于绝大多数分析物，证明了比较方法之间精密度（通常≤5%）和校准性能的统计学等效性。
Three methods for direct solid sampling of bulk material namely IR laser ablation, glow discharge and spark OES, were compared with respect to analytical figures of merit obtained for elemental analysis with atomic spectrometry. Matrices investigated were copper, pressed doped copper powder, and magnesium alloys. For the vast majority of analytes, statistical equivalence regarding precision (usually ≤5%) and the performance of the calibrations between the compared methods was demonstrated.
