使用激光烧蚀（LA）微量取样耦合电感耦合等离子体质谱法（ICP-MS）测定了通常存在于使用“浮法“工艺制造的钠钙玻璃中并用于玻璃样品定量分析和法医比较的十七（17）种主要和痕量元素的一致浓度值。这是首次报告一套新的浮法玻璃的化学表征，该浮法玻璃拟用作LA-ICP-MS使用标准测试方法（ASTM E2927- 16 e1）进行玻璃法医分析和比较的基质匹配校准标准。三种康宁浮法玻璃标准品（CFGS）分别以低、中、高浓度生产，其中32种元素通常在法医案例中的浮法玻璃样品中发现。这项工作描述了七（7）个实验室之间的国际合作，以评估三种玻璃材料的均匀性，并报告了三个浓度水平下17种元素的一致浓度值。使用标准测试分析方法的八（8）组LA-ICP-MS分析的独立结果和一组微X射线荧光光谱法（μXRF）数据（使用方法ASTM E2926-17）在每个实验室内的相对标准偏差（RSD）通常<3%，在所有参与研究的实验室中，使用50 μm -100 μ m之间的采样点的浓度范围的RSD < 5%。直径约100 μm。这些结果表明，新的校准标准品在报告的小采样体积（约90 μm深，直径约80 μm）下对大多数元素都是均匀的，并且在不同的参与实验室之间显示出极好的一致性。使用先前报道的校准标准品（FGS 2）测定一致浓度值，并用NIST 1831 SRM®进行检查。目前正在与美国国家标准与技术研究所（NIST）的科学家合作，以认证这些玻璃为SRM，包括对微量元素和痕量元素含量的定量分析进行认证，供NIST将来分发。
Consensus concentration values for seventeen (17) major and trace elements typically present in soda-lime glass manufactured using the “float ” process and used in the quantitative analysis and forensic comparison of glass samples were determined using laser ablation (LA) micro sampling coupled to inductively coupled plasma mass spectrometry (ICP-MS). This is the first reporting of the chemical characterization of a new set of float glass intended for use as matrix-matched calibration standards in the forensic analysis and comparison of glass by LA-ICP-MS using a standard test method (ASTM E2927–16e1). Three Corning Float Glass Standards (CFGS) were manufactured at low, medium, and high concentrations of 32 elements typically encountered in float glass samples as found in forensic casework. This work describes an international collaboration among seven (7) laboratories to evaluate the homogeneity of the three glass materials and reports the consensus concentrations values of 17 elements at three concentration levels. Eight (8) sets of independent results from LA-ICP-MS analysis using the standard test method of analysis and one set of micro-X-ray Fluorescence Spectrometry (μXRF) data (using method ASTM E2926–17) resulted in typically <3% relative standard deviation (RSD) within each lab and < 5% RSDs among all labs participating in the study for the concentration ranges using sampling spots between 50 μm - 100 μm in diameter. These results suggest that the new calibration standards are homogeneous for most elements at the small sampling volumes (~ 90 μm deep by ~80 μm in diameter) reported and show excellent agreement among the different participating labs. Consensus concentration values are determined using a previously reported calibration standard (FGS 2) and checked with a NIST 1831 SRM®. A collaboration with National Institute of Standards and Technology (NIST) scientists to certify these glasses as SRMs, including the certification of the quantitative analysis of the minor and trace element content, for future distribution by NIST is ongoing.
