Agilent 6400 Series Triple Quadrupole LC/MS System - Quick Start Guide

Importance of the Topic

Liquid chromatography coupled with triple quadrupole mass spectrometry is a cornerstone for trace‐level quantitative analysis in environmental monitoring, pharmaceutical research, food safety and clinical studies. Its ability to selectively isolate precursor ions, generate product ions and monitor multiple reaction transitions provides unmatched specificity and sensitivity.

Study Objectives and Overview

This Quick Start Guide serves as a concise roadmap for initial operation of the Agilent 6400 Series Triple Quadrupole LC/MS system. It covers software launch, instrument configuration, method creation, data acquisition and integrated data analysis using the MassHunter Workstation.

Methodology and Instrumentation

Key procedural steps:

• Launch the Data Acquisition application and configure primary windows for instrument status, chromatogram and spectrum plots, method editing, sample runs and tuning.
• Prepare LC modules by purging pumps, conditioning columns, and switching flow to waste or MS.
• Perform instrument tuning with Checktune for performance verification, Autotune for full parameter optimization or Manual Tune for custom adjustments.
• Create acquisition methods by selecting scan types (MRM, Dynamic MRM, Triggered MRM), defining transitions, setting chromatogram plots, and configuring data analysis parameters.
• Set up and run single samples or automated worklists, integrating quantitative and qualitative analysis workflows.

Instrumentation

The Agilent 6400 Series includes:

• Triple quadrupole/hexapole/quadropole layout for MS/MS fragmentation and separation.
