Identify and quantify individual lipid species or metabolites with long-lasting, stable electrospray from direct extracts of biological samples including extracts from solvents containing chloroform, isopropanol, or methanol. Consistent profile response from reproducible chip-based nano-electrospray without LC separation.

• High throughput sample analysis from 96 or 384 sample plates
• Faster analysis than traditional LC/MS
• No carry-over due to one-sample, one-tip, one-nozzle approach
• Population scale lipidomics and metabolomics studies based on shotgun infusion
• Newborn screening for inborn errors of metabolism
