A major part of mass spectrometry-based analysis is the ability to separate analytes of interest from other analytes and complex matrices. The two most commonly used separation techniques comprise Ultra High-Pressure Liquid Chromatography (UHPLC) and Nano Liquid Chromatography.
Since its inception, UHPLC has shown very high efficiency in separating a wide range of organic compounds. UHPLC can separate many drugs that are not amenable to Gas Chromatography (GC) based separation owing to their polarity, volatility, or high molecular weight. Research laboratories have been successfully implementing nano-liquid chromatography for separation of peptides resulting in confident analysis of protein mixtures or samples with very small concentrations of targeted peptides. The combination of UHPLC or NanoLC with the Thermo Scientific Orbitrap Exploris 480 mass spectrometer results in robust, reliable, reproducible LC-MS assays for every clinical research and forensic toxicology laboratories, regardless of the analyte or matrix complexity and user expertise.
