Chemical ionization mass spectrometers accurately evaluate VOCs in a wide range of environments. The analysis becomes ambiguous when a compound is obscured by either isomeric or isobaric interference.

Every rock on Earth is a time capsule, holding traces of our planet from when the minerals first formed. Consider a smidge of 164-million-year-old clay, says M. Joseph Pasterski, an organic geochemist ...

An initial step of most NMR studies is identifying peaks in the obtained spectrum. Producing a peak list is especially crucial if the spectrum is automatically prepared. Peak picking is still ...
