Abstract Emission spectra of Codonopsis pilosula samples from nine habitats were measured using calibration-free laser-induced breakdown spectroscopy (CF-LIBS) and liquid cathode glow discharge-atomic emission spectrometry (LCGD-AES). Based on the measured spectra, the elements in the samples and the corresponding compositions were determined, and the results were compared with those from inductively coupled plasma mass spectrometry (ICP-MS) by using the Mg/Ca ratios. In addition, an estimation of the plasma parameters was considered and the stability of the results from both analytical methods was discussed.

CF-LIBS和LCGD-AES检测党参样品中镁和钙的对比研究

摘要 使用免校准激光诱导击穿光谱 (CF-LIBS) 和液体阴极辉光放电-原子发射光谱法 (LCGD-AES) 测量了来自九个栖息地的党参样品的发射光谱。根据测量的光谱，确定样品中的元素和相应的组成，并通过使用 Mg/Ca 比将结果与电感耦合等离子体质谱 (ICP-MS) 的结果进行比较。此外，还考虑了对血浆参数的估计，并讨论了两种分析方法结果的稳定性。
