Agilent G6475A and 6495D LC/TQ Site Preparation Checklist

Significance of Topic

Ensuring that triple quadrupole LC/MS systems are installed under optimal conditions is critical to achieving reliable performance, longevity, and return on investment.

Objectives and Study Overview

This guide aims to outline the essential laboratory preparations for installing Agilent G6475A and G6495D LC/TQ instruments. It provides a structured checklist covering space allocation, environmental controls, utilities, consumables, and user responsibilities to facilitate a seamless start-up service.

Methodology and Instrumentation

The site readiness criteria were organized into functional areas: space and weight support, environmental parameters, exhaust and venting, electrical requirements, and gas supply.

• Space and Weight: Bench footprint, clearance, and load capacity.
• Environmental: Temperature, humidity, altitude, and vibration.
• Exhaust: Separate vents, tubing, and flow rates.
• Power: Voltage configuration, grounding, and outlet count.
• Gas Supply: Purity, pressure, fittings, and flow for nitrogen supplies.

Used Instrumentation

• Agilent G6475A LC/TQ system
• Agilent G6495D LC/TQ system
• MS40+ and MS120 foreline pumps
• Agilent Jet Stream, APCI, APPI, MMI, ESI, NSI ion sources

Key Findings and Discussion

Bench Space and Weight:

• G6475A: 84×77.3×47.5 cm, 117 kg; G6495D: 91.5×77.3×47.5 cm, 123 kg.
• Minimum 30 cm clearance on sides and 1 m around for service access.

Environmental Conditions:

• 15–35 °C, <85% RH at 35 °C, non‐condensing, indoor use, altitude up to 3,300–3,700 m.

Exhaust Venting:

• Two independent negative‐pressure vents; ≥30 L/min max for G6475A, ≥50 L/min max for G6495D; 0.5″ ID tubing.

Power Requirements:

• Single‐phase 200–240 VAC or 208‐Y; isolated, noise‐free ground; up to 3,800 VA; two dedicated outlets.

Gas Supplies:

• Main N₂ ≥99.5% purity, 5.5–6.8 bar, 30–50 L/min.
• Collision N₂ ≥99.999% purity, 1–2 bar, ≥0.001 L/min.

Benefits and Practical Applications

Implementing these site preparation steps ensures timely installation, minimizes downtime and service visits, and maximizes instrument uptime and data quality in laboratories handling high‐throughput quantitative analyses.

Future Trends and Opportunities

Emerging practices include integration of smart sensors for real‐time environment monitoring, remote commissioning via digital platforms, predictive maintenance, and automated site readiness validation tools to further accelerate instrument deployment.

Conclusion

A comprehensive site preparation protocol for Agilent G6475A and G6495D LC/TQ systems is essential for optimal performance and long‐term reliability. Adherence to detailed specifications in space, environmental control, utilities, and consumables enables efficient installation and operation.
