FAMEs Fatty Acid Methyl Esters: Mass Spectral Database
This price is valid for United States. Change location to view local pricing and availability.
The database contains linear retention index data, registered using an alkane mixture on an apolar column and using also a FAMEs and a FAEEs (fatty acid ethyl esters) mixture on a polar one. The addition of the retention index data enables more reliable compound matching and identification of unknowns.
While other methods, such as LC-MSMS can be used, when using such a highly selective method technicians can only detect what they are looking for, while when performing broader TIC screening using GC/MS, no information is lost. Applications include building FAMEs profiles of target bacteria (e.g., Pseudomonas aeruginosa).
Each record contains the mass spectrum, searchable structure, chemical information, and LRI retention data
Records indexed by name, molecular weight, and retention time
Highly controlled: Measured on a single instrument in controlled conditions
Quality samples sourced from leading suppliers and manufacturers
