Agilent 7900 ICP-MS

Key Features

• Ultra-High Sensitivity & Ultra-Low Detection Limits: Equipped with an off-axis ion lens and Orthogonal Detector System (ODS), delivering 15× higher signal-to-noise ratio and sub-ppt level detection limits (≤0.05 ppt). Enables precise analysis of elements from lithium (Li) to uranium (U).
• Extreme Matrix Tolerance (UHMI Technology): Integrated with Ultra High Matrix Introduction (UHMI), directly analyzing samples with up to 25% total dissolved solids (TDS) (e.g., seawater, ore leachate). Minimizes dilution steps for improved efficiency and stability.
• ORS4 Helium Collision Cell for Complete Interference Removal: The 4th-generation Octopole Reaction System (ORS4) uses pure helium mode to efficiently eliminate polyatomic interferences without reactive gases. Ensures accurate results in complex matrices (e.g., strong acids, organic solvents).
• Ultra-Wide Dynamic Range (11 Orders of Magnitude): Analyze sub-ppt trace elements to percent-level major elements in a single run. Eliminates the need for segmented analysis, covering the full concentration spectrum from trace impurities to major components.
• Intelligent Automation for Simplified Operation: Powered by ICP-MS MassHunter software, featuring auto method setup, smart tuning and one-click data export. Compatible with the SPS4 autosampler for unattended batch analysis, reducing human error.
• Robust Plasma for Long-Term Stability: Optimized plasma design with a CeO⁺/Ce⁺ ratio of <1%. Signal drift remains <3% during prolonged continuous analysis, suitable for industrial-grade high-throughput QC.

Applications

• Environmental Monitoring: Ultra-trace detection of heavy metals (e.g., Pb, As, Cd) in water, soil and air particulates.
• Food Safety: Screening of harmful and nutritional elements in food and agricultural products, complying with national and international standards.
• Pharmaceutical Compliance: Elemental impurity testing per ICH Q3D/USP <232>, supporting drug quality control and regulatory submissions.
• Semiconductor & Electronics: Monitoring ppq–ppt level impurities in wafers and high-purity reagents to ensure manufacturing yield.
• Geology & Mining: Multi-element quantification in ores, rocks and geochemical samples for resource exploration and grade assessment.
