LCMS systems (Sack et al. Journal of Agricultural and Food Chemistry, 59, 6383-6411, 2011; Mol et al. Analytical and Bioanalytical Chemistry, 403, 2891-2908, 2012). The disks are directly analyzed using transmission-mode direct analysis in real time (DART) ambient pressure desorption ...
I was trying to globally deprotect two acid labile protecting groups and by NMR they are gone but it seems as though my octane ring has opened up my conditions were Dioxane/MeoH/4.0M HCl. Not sure what happened, is anyone familiar with oxetane chemistry? Thanks,...
: Quantitation FAQ © 2009 Matrix Science Quantitation based on the relative intensities of extracted ion chromatograms (XICs) for precursors is known in Mascot as Precursor protocol and by far the most widely used approach, applicable to any chemistry that creates a precursor mass shift. For ...
After protein extraction and digestion of the raw sample into peptides, peptides are desalted and iRT peptides are added just prior to LCMS-DIA analysis as a means of normalizing by retention time. 6.2. Approaches of Normalization of MS-Derived Data Normalization of MS data can be ...
Although cannabinoids such as CBD may have potential for therapeutic promise, scientific evidence supporting their use in animals is currently limited and few well-controlled studies exist, most of which focus on companion animal use. 2.
