Scientists at Shimadzu Scientific Instruments (SSI) say they want you to know more about the fruits of your labour - how they smell and taste, but more specifically, their mass spectra and LRI data.
SSI, one of the leading developers of analytical equipment in the USA, announces the availability of its new flavours and fragrances natural and synthetic compounds (FFNSC-MS) library.
The library contains approximately 1200 mass spectra of various natural and synthetic flavour and fragrance compounds.
The spectra, along with linear retention indexes (LRI) of each compound, were acquired using a Shimadzu GCMS-QP2010 system.
Only pure substances were used so that the library would offer users the highest possible accuracy and reliability.
Shimadzu's GCMSsolution software automatically carries out LRI calculations for each peak of an unknown sample after separation and determination of the hydrocarbon standard using the same column.
The LRI is solely dependent on the type of stationary phase in the column, meaning that column dimensions are irrelevant to calculations.
During the library search, both library spectra and LRI data are compared with the unknown compounds.
"This is extremely helpful for the correct determination of compounds showing very similar fragmentation patterns, such as homologues or isomers of terpenes," said Mark Taylor, product manager of GCMS at SSI.
"When mass spectra and LRI data are combined, identification of unknown compounds reaches an unrivalled level of accuracy."
