Agilent InfinityLab Supplies for the Agilent 1290 Infinity II LC with Multisampler

Significance of the topic

Maintaining high-performance liquid chromatography (HPLC) systems with genuine, manufacturer-specified supplies and parts is essential for achieving reliable, reproducible analytical results. Agilent’s InfinityLab Supplies tailored for the 1290 Infinity II LC with Multisampler ensure system integrity, reduce downtime through preventive maintenance, and uphold data quality in pharmaceutical, environmental, food, and research laboratories.

Objectives and overview

• Provide a categorized quick-reference of the most commonly ordered consumables and preventive maintenance (PM) kits for the Agilent 1290 Infinity II LC with Multisampler.
• Facilitate efficient ordering and inventory management for routine system upkeep.
• Highlight the role of each supply category in maintaining system performance and data integrity.

Methodology and instrumentation

• Instrument: Agilent 1290 Infinity II LC system equipped with high-speed, binary/quaternary and flexible pumps, multisampler, diode array detector (DAD), visible-UV detector (VWD), and optional thermostatted multicolumn switching.
• Approach: Organize consumables into supply categories—general pump, high-speed pump, flexible pump, detector, multisampler, multicolumn thermostat, capillaries and fittings, and general supplies/kits.
• Preventive maintenance strategy: Each PM kit includes seals, frits, gaskets, and other wear components, with optional parts specified for specialized configurations.

Main findings and discussion

• General pump supplies cover solvent inlet filters, tubing kits (standard and ultra-clean for MS), peristaltic pumps, and wash/seal lines to support reliable fluid handling.
• High-speed and flexible pump kits ensure consistent mixing and pressure delivery, using gold and PEEK seals, frits, jet mixers, and purge valve components.
• Detector supplies for DAD and VWD include deuterium lamps with RFID, flow cells of various path lengths and volumes, and repair kits to maintain optimal sensitivity and baseline stability.
• Multisampler components—needle assemblies, rotor seals, metering seals, sample loops, and drawer kits—support high throughput and low carryover in automated injection.
• Capillaries, fittings, connectors, and inline filter kits enable leak-free fluid paths and rapid system configuration changes.

Benefits and practical use

• Streamlined ordering process reduces downtime by ensuring critical parts are available before failure occurs.
• OEM-certified supplies minimize variation, protect against contaminants, and extend component life, improving data consistency and method robustness.
• Comprehensive PM kits simplify maintenance workflows, lowering total cost of ownership and preventing unscheduled service disruptions.

Future trends and opportunities

• Integration of RFID-enabled parts and digital notifications could further automate maintenance scheduling and inventory tracking.
• Advancements in ultra-low dead-volume fittings and microfluidic connectors may enhance performance for capillary and nano-LC applications.
• Expansion of inline component diagnostics, including pressure and flow monitoring, could predict part wear and optimize replacement intervals.

Conclusion

Agilent InfinityLab Supplies for the 1290 Infinity II LC with Multisampler provide a structured, quality-assured portfolio of parts and kits designed to maximize uptime, data quality, and method reproducibility. Adopting genuine supplies and preventive maintenance kits strengthens laboratory efficiency and supports the rigorous demands of modern analytical workflows.
