ISO 15632:2021 微光束分析.带半导体探测器能量发散X射线分光仪的仪器规范

This document defines the most important quantities that characterize an energy-dispersive X-ray spectrometer consisting of a semiconductor detector, a pre-amplifier and a signal-processing unit as the essential parts. This document is only applicable to spectrometers with semiconductor detectors operating on the principle of solid-state ionization. This document specifies minimum requirements and how relevant instrumental performance parameters are to be checked for such spectrometers attached to a scanning electron microscope (SEM) or an electron probe microanalyser (EPMA). The procedure used for the actual analysis is outlined in ISO 22309[2] and ASTM E1508[3] and is outside the scope of this document.

T/CCASC 3001-2020 氯化石蜡产品中短链氯化石蜡检测方法

氯化石蜡的生产方法是基于烷烃（主要是正构烷烃）的加氯反应，本方法分析氯化石蜡产品中的短链氯化石蜡，通过催化剂将氯化石蜡在线催化脱氯加氢，还原成相应的烷烃，然后用气相色谱-氢火焰离子化检测器测定烷烃。采用内标法对还原产生的碳链长度为10-13的烷烃进行定量分析，并结合氯含量信息，计算出样品中短链氯化石蜡的含量水平。

BS ISO 20720:2018 微束分析 使用 WDS 和 EDS 分析一般粉末的样品制备方法

What is this standard about? This document specifies specimen preparation methods for the analysis of particles in powders using energy-dispersive spectrometers (EDS) or wavelength-dispersive spectrometers (WDS) installed on an EPMA or SEM. The preparation methods for powder particle analysis are classified by the analytical purpose and the particle size. This document applies to inorganic particles larger than 100 nm and smaller than 100 µm in diameter. It applies only to analysis of “general” powders, which means that it excludes procedures for special applications such as forensic or trace analysis.

T/GDTL 005-2018 聚酯树脂锡元素限量及测试方法

4　限量要求 无锡聚酯树脂中锡元素限量为≤10mg/kg。 注1：需要明确的是，对公众健康和环境构成较大风险的是有机锡化合物，无论是否制定标准限制其使用，涂料及其原材料生产者均应采取措施尽量减少有机锡化合物的使用。 注2：因有机锡化合物溶解在聚酯树脂等有机物中，通常测试方法结果存在较大的不确定性，因此本标准采用限制无锡聚酯树脂中总锡含量的方法来限制其有机锡化合物含量。 注3：聚酯树脂中锡元素含量高于本标准限值时，不能确定一定不满足相关法规要求，需要进一步测试分析其中锡元素的存在形式。 5　测试方法及原理 参照GB/T 30903，采用电感耦合等离子体质谱法测试聚酯树脂中锡元素含量。 试样经处理后的溶液由载气（氩气）引入雾化系统进行雾化后，以气溶胶形式进入等离子体中心区，在高温和惰性气氛中被去溶剂化、汽化解离和电离，转化成带正电荷的正离子，经离子采集系统进入质谱仪，质谱仪根据质荷比进行分离，离子信号由电子倍增器接收，经放大后进行检测。根据锡元素质谱峰强度，对其进行定量分析。
