The Quattro II gives investigators access to a powerful technology for the analysis of complex lipids, intact proteins, and peptide mixtures. This instrument has the advantage of precise mass measurement at the lower mass range of many lipids coupled with the capability for precursor and neutral loss analysis to identify phospholipid subclasses. Product ion analysis is used to identify the fatty acids carried by the phospholipid. The Quattro II was purchased with grant funds from the NSF Academic Research Infrastructure Program and matching Institutional funds. It was updated with funds from the North Carolina Biotechnology Center and the Winston-Salem Foundation. |
