{Reference Type}: Guideline {Title}: Guidelines for LC-MS identifications of flavoring substances in nature, made by the Working Group on Methods of Analysis of the International Organization of the Flavor Industry (IOFI). {Author}: ; {Journal}: Mol Nutr Food Res {Volume}: 54 {Issue}: 2 {Year}: Feb 2010 {Factor}: 6.575 {DOI}: 10.1002/mnfr.200900501 {Abstract}: These guidelines are intended to assist authors and reviewers of publications concerning the validity of identifications of flavouring substances in nature using LC-MS. They address the choice of the transition between precursor and product ions (with examples using the "Identification Point" concept), the tolerances for ion-abundance ratios, and the importance of performing blank experiments.
