ocr: CELIAS MTOF has measured rare elements and isotopes that were previ- ously not resolvable from more abundant neighbouring species, or were not previously observable at all. (Phosphorus, chlorine, po- tassium, titanium, chromium and nickel have been measured in the solar wind for the first time.) The isotopic data of several re- fractory elements showed no sign of significant isotopic fractiona- tion between the solar and Solar Wind Elements/Isotopes observed by CELIAS MTOF terrestrial ma- dene: CNONe NaME AISI ps OAr B TCMnte N terials.
