Agilent 7700X ICP-MS Inductively Coupled Plasma Mass Spectrometer Introduction

Product Overview

The Agilent 7700X is a versatile inductively coupled plasma mass spectrometer (ICP-MS) that combines high-temperature plasma ionization technology with the high-sensitivity detection capabilities of quadrupole mass spectrometry. Designed for rapid analysis of trace and ultra-trace elements in complex matrix samples, it meets the needs of routine laboratories while handling challenging high-salt samples. Widely used in environmental monitoring, food safety, semiconductor materials, geological exploration, and biomedical research, the 7700X delivers reliable performance across diverse applications.

Core Technical Features

1. High Sensitivity & Interference Removal

   • Equipped with a third-generation Octopole Reaction System (ORS3), which eliminates polyatomic interferences using only helium (He), achieving an oxide ratio (CeO+/Ce+) as low as 1.5%.
   • Exceptional sensitivity: ≥50 Mcps/ppm for low-mass elements (Li), ≥160 Mcps/ppm for mid-mass elements (Y), with detection limits reaching sub-ppt levels (e.g., Be ≤0.5 ppt).
   • High-temperature ion source and High Matrix Introduction (HMI) system support a 9-order dynamic linear range, capable of analyzing samples with up to 3% total dissolved solids (TDS).

2. Smart & Efficient Operation

   • Features a digitally controlled RF generator and auto-tuning function, simplifying method development and reducing training requirements.
   • Quick-maintenance design: One-click sampler cone removal, and a nebulizer system compatible with acid/ultrasonic cleaning (PFA or quartz).

3. Versatile Expandability

   • Optional interfaces for chromatography coupling (e.g., LC-ICP-MS), organic solvent direct injection kits, and inert acid-resistant systems for speciation analysis.
   • MassHunter software integrates real-time quality control (QA/QC) and semi-quantitative analysis, enabling 70-element screening in under 30 minutes.

Typical Applications

• Environmental Monitoring: Detection of heavy metals (As, Pb, Hg) and persistent pollutants in water and soil.
• Semiconductor Industry: Ultra-trace impurity analysis (Na, K, Ca) in high-purity reagents (HF, peroxides).
• Biomedical Research: Trace element analysis in biological samples (blood, urine).

Industry Advantages

The 7700X is renowned for its modular design and low maintenance costs. Its helium-only collision mode significantly reduces operating expenses, while its compact size (one of the smallest commercial ICP-MS systems) saves lab space. Compared to the previous 7500 series, it offers enhanced speed, interference removal, and stability.

Note: For optimal performance, use high-purity helium (≥99.999%) and operate in a temperature-controlled environment (15-35°C).
