SEM analysis of the fracture surface of blocs MD1, MD2 and MD3 was performed using a JSM5910LV equipped with a ThermoScientific SDD detector for energy dispersive X-ray (EDX) analysis. The SEM was operated in low vacuum (30 Pa) at 20 Kv using backscatter electron mode.
Sdd detector
Manufactured by Thermo Fisher Scientific
The SDD detector is a type of energy-dispersive X-ray spectroscopy (EDS) detector used in electron microscopy applications. It is designed to detect and analyze the characteristic X-rays emitted by a sample during electron beam bombardment, allowing for the identification and quantification of the elements present in the sample.

Few fibres, from the 28 selected experimentally-dyed samples (prior to ageing) and from the historical samples, were fixed on carbon adhesive over aluminium stubs for SEM-EDX analyses. Samples were observed with a SEM, JSM5910LV from JEOL, to assess possible contaminating particles on the textile fibres, using 20 kV accelerating voltage, 11 mm working distance, 48 spotsize, and backscattered signal (BES) at 40 Pa. EDX analyses were undertaken using a SDD detector from Thermo Fisher scientific and a NSS software. Analyses were undertaken on regions free of contaminating particles to evaluate the presence of mordants and additives, using 80 s live time and pulse processor with projected maximum throughput of 71400 cps. Owing to the non-uniform surface and variable thickness of the fibres, EDX analyses were performed three times for each sample, to obtain a qualitative assessment of the elements present.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
