The use of laser ablation inductively coupled mass spectrometry (laser ICP-MS), in combination with a calibration procedure involving the addition of enriched isotopes, for the determination of trace elements in birch leaves and their ashes is described. Samples are pressed into pellets without binder materials and analyzed using the ICP-MS spectrometer ELAN 5000 with the laser sampler type 320 (Perkin Elmer). The analytical results obtained by two methods are compared with the values obtained after digestion of the same samples and analysis of the resulting solutions by ICP-MS. The results are discussed in terms of precision, accuracy and limits of detections.
描述了使用激光烧蚀电感耦合等离子体质谱法（激光ICP-MS），结合涉及添加富集同位素的校准程序，来测定桦树叶及其灰烬中的微量元素。将样品在不使用粘结剂材料的情况下压制成小球，并使用配备320型激光采样器（珀金埃尔默公司）的ICP-MS光谱仪ELAN 5000进行分析。将两种方法获得的分析结果与相同样品消化后通过ICP-MS分析所得溶液获得的值进行比较。从精密度、准确度和检测限方面对结果进行了讨论。
