Agilent 240-MS GC/Ion Trap Mass Spectrometer Introduction

Product Overview

The Agilent 240-MS is a gas chromatography-ion trap mass spectrometry (GC/MS) system featuring a 3D ion trap mass analyzer, delivering ultra-high sensitivity and multi-stage MSⁿ capabilities for qualitative and quantitative analysis of trace compounds in complex matrices. Developed by Agilent Technologies (China), this system is widely used in environmental monitoring, food safety, pharmaceutical research, and clinical studies, excelling in unknown compound screening and structural elucidation.

Core Technical Features

1. Ultra-High Sensitivity & Multi-Stage MSⁿ Capability

   • Triple Resonance Scanning Technology (patented design) significantly improves resolution, eliminating molecular ion interference, and supports up to 10-stage MSⁿ for richer structural information.
   • Full-Scan Sensitivity: Detects 200 fg octafluoronaphthalene (OFN) in EI mode (S/N >20:1) and 1 pg decafluorobenzophenone (S/N >50:1) in CI mode.

2. Flexible Ionization & Scanning Modes

   • Supports electron ionization (EI) and chemical ionization (CI) with automatic switching; unique Pulsed Negative/Positive Chemical Ionization (PNHCI) enables mixed-mode analysis for diverse applications.
   • Scanning functions include full scan (Scan), selected ion monitoring (SIM), and multiple reaction monitoring (MRM), with automatic switching for enhanced selectivity in complex matrices.

3. High-Efficiency GC System

   • Paired with the Agilent 7890B GC, it supports three-channel independent analysis (3 inlets + 3 × 100m capillary columns), 24-step temperature programming, and an oven range of 4–450°C for high-throughput analysis.
   • Pulsed ionization mode adjusts emission current based on sample concentration, reducing ion source contamination and extending filament life.

Typical Applications

• Environmental Analysis: Detection of trace pollutants like dioxins in air and PAHs in soil.
• Food Safety: Screening of pesticide residues or food additives in agricultural products.
• Pharmaceutical R&D: Structural analysis of synthetic intermediates or genotoxic impurities.

Industry Advantages

The 240-MS features an "all-inert ion trap" design for analyzing highly reactive compounds, with triple resonance technology and multi-stage MSⁿ outperforming traditional quadrupole MS in sensitivity and selectivity. Its modular design supports upgrades to comprehensive two-dimensional GC (GC×GC) for ultra-complex samples.

Note: Operate in a temperature-controlled (16–30°C), low-vibration environment with helium (99.999%) as the carrier gas for optimal performance.
