Search the LIPID MAPS® Partial Spectra Database with a list of precursor ions
Please select search type below
Enter the name you want to search in lipid and part name fields e.g. 16:0_20:3
Enter the precursor m/z value you want to search e.g. 727.5632
Enter a list of neutral loss values separated by comma or space e.g. 18.01, 180.6
To simplify the Neutral Loss search function, the tolerance of Neutral loss is set to +/- 0.5 m/z. So you can use 18 or 18.01 for a neutral loss of water and 180 or 180.06 for the neutral loss of a monosaccharide (C6H12O6).
Enter a list of product ion m/z values separated by comma or space e.g. 368.2437,448.2100
