Dear Testers:
I have referred to Appendix 4 on page 53 of the ECAT Report dealing with the ICP-MS and ICP-AES analysis of the fuel and the ash. The last paragraph on this page states that the fuel contained high concentrations of the elements C, Ca, Cl, Fe, Mg, Mn but these were not found in the ash. As I'm sure you are aware Inductively Coupled Mass Spectrometry is very sensitive being able to detect metals as well as some non metals down to 1 part per trillion. (One part in 10 to the minus 12).
Do you have any explanation why these elements were totally absent in the ash. Is it possible that the sample size was too small?
