New reaction system said to achieve up to 100% interference reduction for trace element analysis of complex matrix samples like seawater, wastewater, urine, and blood
Agilent Technologies Europe says that its new Octopole reaction system can significantly attenuate troublesome interferences, thereby allowing for accurate trace metals determinations in complex sample matrices.
The Agilent 7500c inductively coupled plasma mass spectrometer has been demonstrated to be effective for the analysis of trace metals in such complex matrices as seawater, wastewater, urine, and blood.
The new Octopole reaction system, standard in the Agilent 7500c, significantly reduces interferences arising from the sample matrix without compromising ease of use, throughput or the multi-element capability that characterises traditional ICP-MS performance.
A novel off-axis ion optic system and an octopole reaction cell provide up to 100% rejection of interferences while retaining the sensitivity required for ultra-trace analysis.
The Octopole reaction system uses low reactive gases such as hydrogen and helium which do not form the unpredictable cluster interferences characteristic of more reactive gases such as ammonia.
This greatly simplifies instrument optimisation and subsequent analysis even when working with uncharacterised or complex sample types.
The Agilent 7500c also features an open-architecture sample introduction system for ease of maintenance, a robust 27.12MHz solid state RF generator, a high-frequency mass analyser, and a high-speed dual-mode detector providing nine orders of linear dynamic range.
