7900 ICP-MS

The Agilent 7900 ICP-MS is a flexible single quadrupole ICP mass spec instrument that provides the industry’s best matrix tolerance, most effective helium collision mode, lowest detection limits, and widest dynamic range. As a result, you can be confident you are reporting accurate data every time, even at trace levels, whatever your sample types.

The 7900 ICP Mass Spec provides the highest performance for demanding commercial and industrial applications, with the high sensitivity and fast acquisition of transient signals – necessary for analysis of single nanoparticles (spICP-MS), single cells, and for laser ablation. In addition, having the flexibility needed for research and advanced analysis, such as speciation, is sure to give you the edge over the competition.

How It Works

ICP-MS is an analytical technique used to measure the concentration of metals and other elements. Samples are usually introduced as liquids, but ICP-MS can also be used to measure elements in solid materials and gases. ICP-MS consists of a high temperature ion source (the plasma), a mass spectrometer (usually a quadrupole mass filter), and a detector. The plasma is at atmospheric pressure and the spectrometer and detector are in a vacuum chamber, so an ICP-MS instrument also needs an interface and ion lens to transfer the ions through the system.

A liquid sample is pumped through a nebulizer to form an aerosol that is carried in a gas stream to the plasma. The plasma is a high temperature electrical discharge which vaporizes the sample material and then atomizes and ionizes the elements. The ions pass through an interface into a vacuum chamber, where they are separated from photons, neutral particles, and interfering ions using an ion lens and a collision/reaction cell (CRC). The analyte ions are then sorted by the quadrupole mass filter and each mass is passed to the detector to be counted.

ICP-MS is used for multielement analysis in practically all industries from food safety, environmental monitoring, and pharmaceutical testing, to semiconductor manufacturing, geochemical analysis, and life science research. ICP-MS measures each sample in around 3 minutes, so it is particularly beneficial in high-throughput laboratories. ICP-MS can quantify nearly every element (and measure isotopic composition) at concentrations from parts per trillion to percent and it can also be connected to a chromatographic system for speciation analysis.

Applications

Fully integrated support for multielement speciation analysis using HPLC-ICP-MS

The Agilent 7900 ICP-MS provides the flexibility to address your most demanding applications. Fully supported connection and integrated software control for Agilent LC systems provides routine, high performance speciation analysis capability. Other chromatographic separations (such as GC, CE and FFF) are also supported.

Advanced HPLC-ICP-MS capabilities include automatic switching of columns and mobile phases, which enables multiple HPLC-ICP-MS methods to be run in a single, unattended sequence.

Flexible configurations and high performance to address advanced ICP-MS applications

The 7900 provides the flexibility to address your most demanding applications. Effective control of interferences with the ORS4 collision/reaction cell and the industry’s most effective cool plasma allow ultratrace analysis of high purity process chemicals. Optional sample introduction kits enable routine analysis of organic solvents and corrosive samples such as HF.

Easy connection to third party peripherals such as laser ablation (LA-ICP-MS) enables direct, high-sensitivity analysis of solids.

High sensitivity and fast signal acquisition for single nanoparticle (sNP) analysis

High sensitivity is the most important factor for detecting the smallest nanoparticles (NPs) and is critical for the best spatial resolution in laser ablation (LA) ICP-MS imaging applications.

The 7900 provides superior sensitivity across the mass range, combined with optimized 0.1 ms dwell time for fast time resolved analysis (TRA) acquisitions. High sensitivity is combined with the most robust plasma in the ICP-MS industry, and the widest detector dynamic range for easy analysis of major elements.
