\newpage  \section{WM4}  \subsection{Mass Spectrometry}  Mass spectrometry is used to find the atomic mass and relative abundances of isotopes in an element.   \begin{itemize}  \item Fragmentation pattern  \begin{itemize}  \item Strongest peak calibrated to 100\%  \item Molecular ion peak may be too low to see  \begin{itemize}  \item Molecule with only one electron removed, $M^+$  \end{itemize}  \end{itemize}  \item Peak at $M+1$ due to Carbon-13  \begin{itemize}  \item 1.1\% of Carbon is Carbon-13  \end{itemize}  \item All molecules and fragments are ionised  \begin{itemize}  \item Msut be denoted with charge of +1  \end{itemize}  \item Groups can be conspicuos by absence  \end{itemize}
