ANSI/ASTM D6247:1998 通过X射线荧光光谱法对聚烯烃中元素含量分析的试验方法

This test method covers a general procedure for the determination of elemental content in polyolefins by X-ray fluorescence spectrometry, in concentration levels typical of those contributed by additives and reactor processes. Note 1 -Specific methods and capabilities of users may vary with differences in interelement effects and sensitivities, instrumentation and applications software, and practices between laboratories. Development and use of test procedures to measure particular elements, concentration ranges or matrices is the responsibility of individual users. Note 2 -One general method is outlined herein; alternative analytical practices can be followed, and are attached in notes, where appropriate. The values stated in SI units are to be regarded as the standard. The inch-pound units given in brackets are for information only. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 10. Note 3 -There is no similar or equivalent ISO standard.
