mass

Common mass spectrometry tools described in John Roboz (2013) <doi:10.1201/b15436>. It allows checking element
isotopes, calculating (isotope labelled) exact monoisitopic mass, m/z values and mass accuracy, and inspecting possible contaminant mass peaks,
examining possible adducts in electrospray ionization (ESI) and matrix-assisted laser desorption ionization (MALDI)
ion sources.

<dd>if case sensitive is `FALSE` (default), the elements are seperated by numbers.
for instance, Carbon dioxyde can be written as 'c1o2' or any combination of the two elements in lower or
upper cases. However, the number of elements should be clearly stated in the chemical formula. if case
sensitive is `TRUE`, the elements are seperated by upper case letters. For instance, Carbon dioxyde must
be written as 'C1O2' or `CO2`. You don't meed to write the number of the element if it is 1.</dd></dl>
