Doubts are increasingly being exp

    30、ressed about the negative impact which rubber containing certain antidegradants can have on the environment. However, demonstrating the presence of antidegradants in rubber products is not easy.There are methods of qualitative analysis, specified in International Standards such as ISO 4645, which us

This requires a highly skilled operator with a great amount of knowledge and experience, as well as the use of standard reference materials.The gas chromatography/mass spectrometry technique specified in this document is an efficient method suitable for identifying antid
