Detailed Introduction
The Agilent 6530 Accurate-Mass Quadrupole Time-of-Flight (Q-TOF) LC/MS System is a high-performance liquid chromatography mass spectrometry platform designed for accurate mass analysis, structural identification, and comprehensive profiling of complex samples. It combines Agilent’s advanced quadrupole technology with high-resolution time-of-flight (TOF) detection, providing excellent mass accuracy, sensitivity, dynamic range, and reliable performance for applications in pharmaceutical research, biotechnology, metabolomics, proteomics, environmental analysis, and food safety.
The Agilent 6530 Q-TOF LC/MS delivers accurate mass measurement with high-resolution MS and MS/MS capabilities, enabling researchers to identify unknown compounds, characterize metabolites, and confirm molecular structures with confidence. The system typically achieves mass accuracy within a few ppm, making it suitable for demanding applications requiring precise molecular formula determination.
Equipped with Agilent’s Jet Stream electrospray ionization (ESI) technology, the 6530 Q-TOF provides enhanced ion transmission efficiency and improved sensitivity compared with conventional ESI sources. The instrument supports both positive and negative ion modes, allowing flexible analysis of a wide range of chemical compounds, including small molecules, peptides, proteins, and complex biological samples.
The quadrupole mass filter enables targeted precursor ion selection, while the TOF analyzer provides rapid full-spectrum acquisition and high-resolution detection. This combination allows the system to perform advanced MS/MS experiments, accurate mass database searching, and unknown compound identification. The high-speed acquisition capability is especially valuable for LC/MS workflows involving fast chromatography and complex sample matrices.
The Agilent 6530 Q-TOF LC/MS is commonly paired with Agilent Infinity LC systems and MassHunter software, providing an integrated solution for instrument control, data processing, qualitative analysis, and quantitative workflows. Its user-friendly software environment supports automated data interpretation, molecular formula generation, isotope pattern matching, and library searching.
Used Agilent 6530 Q-TOF LC/MS systems remain popular in laboratories worldwide because of their strong analytical performance, robust design, and excellent serviceability. They provide an economical solution for laboratories seeking high-resolution mass spectrometry capabilities without investing in a brand-new instrument.
