Varian 920-LC: Performance and Flexibility in Liquid Chromatography
The Varian 920-LC is a fully integrated analytical HPLC system, factory pre-configured and tested. Designed to efficiently meet laboratory separation needs, it offers easy installation and intuitive operation. Suitable for both routine analyses and complex methods, it is used across various sectors such as pharmaceuticals, environmental testing, chemicals, and food industries.
The 920-LC delivers outstanding performance through its dual-piston solvent delivery system, ensuring virtually pulse-free flow and highly reproducible gradients. Accurate mobile phase mixing enhances result fidelity without requiring premixed solvents. The integrated degasser improves flow stability and significantly reduces detector noise.
The built-in autosampler increases productivity by automating sample introduction. It accommodates up to 200 vials (2 mL) or three 96-well plates. The external needle wash between injections minimizes carryover, ensuring reliable results even for low-concentration samples.
Multiple detector modules are available, including UV-Vis, PDA (diode array), fluorescence, refractive index (RI), and evaporative light scattering (ELS). For example, the UV-Vis detector offers an excellent signal-to-noise ratio and supports a broad wavelength range (190 to 900 nm for PDA version), with time-programmed wavelength control for optimized detection.
Thanks to its temperature-controlled column compartment and low-volume preheater, thermal stability is ensured for enhanced retention time reproducibility. These features are essential for regulated environments or the analysis of thermosensitive compounds.
The Galaxie™ software provides centralized instrument control, customizable report generation, performance tracking, and secure data access, fully compliant with FDA 21 CFR Part 11 requirements.
Scalable and configurable to meet specific needs—whether for method development, production, or regulated environments—the Varian 920-LC is a comprehensive, precise, and reliable HPLC system for mastering liquid chromatography.
