With no GC in front of the mass spectrometer, how can the MS-200 analyse a mixture of different organic compounds?
Kore has developed mixture decomposition software within the GRAMS 32 environment. It uses a least squares method to match fragment patterns with those in a reference database, and thus identify and quantify components in complex mixtures. The “fingerprint” spectra used in the reference database can be produced by the user’s MS-200 on a ‘pure’ compound or can be imported from an electron impact (EI) database like the NIST mass spectral database.
