Flavors for foods and beverages and fragrances for cosmetics and toiletries are complex mixtures made from natural or synthetic compounds. The FFNSC GC/MS Library is specialized for 1,156 flavor and fragrance compounds and contains mass spectra as well as retention indices.
Conventional library search, making use of solely spectral similarity, often indicates so many probable candidates for an unknown that it is hard to identify especially in the case that sample includes isomers and much matrix.
The GCMSsolution provides "similarity search with retention index", using retention indices registered in the FFNSC GC/MS Library. This function makes it possible to perform more reliable and easier search even for complex samples. The results can be output as reports in electronic or hardcopy.
The mass spectra and retention indices registered in the FFNSC GC/MS Library were obtained using the Shimadzu GCMS-QP2010.
*The GC/MS data for the FFNSC Library were obtained by the Prof. Mondello group of the University of Messina in Italy. This was done using the SLB-5ms column (length 30m x inner diameter 0.25mm x film thickness 0.2µm) made by Supelco. The copyright is owned by Avantech Italy.
*The FFNSC GC/MS Library can be used for GCMSsolution Ver 2.4 or higher, or Ver 1.2 su1 or higher. The GCMSsolution Ver 2.4 or higher is required in order to use similarity search with retention index.
*A retention index is information unique to a compound for a given analytical column. A unique index value is assigned to a compound based on its retention time relative to those of an alkane series. The analysis using n-alkane standard mixture is required for determination of the retention indices for unknown samples. The n-alkane standard mixture is required to be purchased separately.
