本报告概述了在VAMAS TWA 2（表面化学分析）主持下进行的实验室间研究中的分析方案，用于使用聚乙烯对XPS仪器进行强度校准。该方案涉及使用低密度聚（乙烯），用干净的手术刀刮除表面氧，作为二级校准标准。对于单色Al K（α）源，所获得的光谱与旋转生成的聚（乙烯）参考光谱结合使用，以确定代表性的透射函数。一个合理的函数，然后拟合产生一个无噪声的连续传输函数的描述，可用于强度校正光谱从其他材料。参与者还将从溅射清洁的黄金中获得光谱，用于验证目的。本报告将指导VAMAS参与者完成样品制备、校准过程和结果报告。对于非单色源，该研究将能够评估聚乙烯是否也可用作二级校准标准。
This report outlines the protocol for analysis in an interlaboratory study conducted under the auspices of VAMAS TWA 2 (Surface Chemical Analysis) for the intensity calibration for XPS instruments using polyethylene. The protocol involves using low-density poly(ethylene), scraped with a clean scalpel to remove surface oxygen, as a secondary calibration standard. For monochromated Al K(alpha) sources, the acquired spectrum is used in conjunction with a mathematically-generated poly(ethylene) reference spectrum to determine a representative transmission function. A rational function is then fitted to produce a noise-free continuous transmission function description which can be used to intensity-correct spectra from other materials. Participants will also acquire a spectrum from sputter cleaned gold for validation purposes. This report will guide VAMAS participants through the sample preparation, calibration process, and reporting of their results. For unmonochromated sources, the study will enable an assessment of whether poly(ethylene) could also be used as a secondary calibration standard.
