Agilent 1260 Infinity Bio-inert Quaternary LC Supplies

Significance of the Topic

The Agilent 1260 Infinity Bio-inert Quaternary LC system is widely used in bioanalysis and pharmaceutical research, where surface interactions between analytes and metal components must be minimized. High-purity, bio-inert fluidic path components play a critical role in maintaining sample integrity, reducing carryover, and extending instrument uptime.

Objectives and Overview

This quick reference guide aims to consolidate the most commonly ordered supplies and spare parts for the 1260 Infinity Bio-inert Quaternary LC system. By listing part numbers and component descriptions in one place, the guide supports fast ordering, minimizes instrument downtime, and helps laboratories maintain consistent performance.

Methodology

The original document compiles Agilent’s inventory of bio-inert pump components, autosampler parts, column compartment valves, detectors, flow cells, capillaries, and tubing. Components are grouped by functional module (pump, autosampler, detector, column compartment, accessories) to match service and maintenance workflows.

Used Instrumentation

Core system: Agilent 1260 Infinity Bio-inert Quaternary LC with modules for binary/quaternary mixing and bio-inert flow paths.

• Pump supplies: bio-inert purge valve, inlet/outlet ball valves, sapphire piston, PTFE seals, support rings.
• Manual injection: bio-inert rotor seal, stator, ceramic stator face.
• Autosampler parts: two-position/six-port seals and stators, needle assemblies, seat assemblies, sample loops, Multi-Draw Kit.
• Column compartment valves: two- and four-port bio-inert rotor seals, stators, stator faces.
• Detectors and flow cells: long-life deuterium and tungsten lamps, HiS deuterium lamp, bio-inert flow cells for UV, fluorescence (FLD), Max-Light cartridges.
• Capillaries and tubing: Titan and PEEK/stainless steel capillaries in various lengths and IDs, inline pressure relief, union fittings.

Main Results and Discussion

Although not an analytical study, the guide highlights the breadth of genuine Agilent bio-inert supplies designed to preserve sample fidelity and system reliability. Centralized part numbering reduces ordering errors, and RFID-enabled lamps and cells simplify maintenance tracking. The modular layout supports targeted servicing and rapid replacement of wear parts.

Benefits and Practical Applications

• Maintains bio-inert flow paths to prevent metal adsorption of biomolecules.
• Extends maintenance intervals and reduces unscheduled downtime.
• Supports method robustness in pharmaceutical QC, proteomics, and clinical assays.
• Ensures compatibility and performance consistency across modules.

Future Trends and Potential Uses

Advances in materials science may bring new low-adsorption coatings and intelligent components with embedded sensors for predictive maintenance. Integration of cloud-based ordering and inventory management could further streamline supply chains. Expanding bio-inert technology to ultra-high-pressure LC and microfluidic platforms will broaden analytical capabilities in proteomics and metabolomics.

Conclusion

The Agilent 1260 Infinity Bio-inert Quaternary LC Supplies quick reference guide provides a comprehensive, module-organized list of parts critical for maintaining bio-inert operation and peak system performance. By centralizing part numbers and descriptions, the guide simplifies procurement, maintenance, and inventory management for high-throughput bioanalysis labs.
