Agilent HP1090 LC

This Agilent HP1090 LC is a used high performance liquid chromatography system built during the era when Hewlett-Packard pioneered modular, computer controlled analytical instrumentation. The unit has been inspected and remains functional for routine liquid chromatography workflows, with the solvent delivery, autosampler, and detector modules working together to deliver reproducible separations. It is a solid choice for labs that already run legacy HP1090 methods or that need a dependable backup system without investing in a brand new platform. The HP1090 was engineered for accurate gradient formation and stable flow delivery, and it continues to serve well in quality control, academic, and research settings where established methods have already been validated on this platform. Its design supports a variety of detector configurations, allowing users to adapt the system to UV, diode array, or other detection needs depending on the application. Because it is a mechanically robust and well understood platform, service parts and technical know-how remain available in the secondary market. This system is well suited to laboratories performing pharmaceutical, chemical, or environmental analyses that rely on classic HPLC separations rather than ultra high pressure techniques. Buyers should expect a pre-owned instrument with normal signs of use, and it is recommended to have the unit calibrated and qualified upon installation. It represents a cost effective way to add or replace HPLC capacity while retaining compatibility with familiar HP chromatography methods.
