Agilent 6495 triple quadrupole LC/MS system: Intelligence That Inspires Confidence

Importance of Topic

Modern analytical laboratories must combine high sensitivity, robustness, and streamlined workflows to address increasingly stringent regulatory requirements and complex sample matrices. Advanced triple quadrupole LC/MS systems empower scientists to deliver reliable, reportable data quickly, even in high-throughput or novice-operated environments.

Goals and Overview

This study introduces the Agilent 6495 triple quadrupole LC/MS system as a cornerstone for building tomorrow’s lab. Key objectives include minimizing detection limits, maximizing uptime, simplifying maintenance, and embedding intelligence for proactive system health monitoring and automated decision making.

Methodology and Instrumentation

The 6495 LC/TQ combines submillisecond dwell times with dual-stage Agilent iFunnel technology to capture more ions and achieve up to tenfold signal improvement without sacrificing precision. A tapered, curved hexapole collision cell refocuses fragment ions and suppresses chemical noise, while an octapole guide transmits a broad m/z range—from small molecules to polymers.
