Thermo Fisher Scientific LipidSearch 5.2.7: Comprehensive Software for Automated Lipid Identification & Quantification

Thermo Fisher Scientific LipidSearch 5.2.7 is a specialized software application for the automated identification and quantification of lipids from liquid chromatography-tandem mass spectrometry (LC-MS/MS) data. It is part of Thermo Fisher’s software ecosystem, designed to process data collected from Thermo Scientific mass spectrometers (Orbitrap, Triple Quadrupole, etc.) and other vendor instruments (AB Sciex, Bruker, Waters, Agilent, Shimadzu, etc.) where supported.

LipidSearch enables high-throughput lipidomics analysis by automatically identifying lipid species based on accurate mass, MS/MS fragmentation patterns, and retention time, while allowing user-defined customization of peak detection and identification parameters.
