Laser Ablation Icp Ms Agilent

Nevertheless for in situ analyses using laser ablation systems both icp mc ms and icp quadrupole ms usually have high signals of 204 pb because of 204 hg interference from the ar gas.

Laser ablation icp ms agilent. Field proven connection kits for lc icp ms and gc icp ms ensure that your speciation applications can be run reliably and reproducibly. Laser ablation icp ms la icp ms is used for the elemental analysis of solid samples and powders including geological materials ceramics biological tissue and forensic samples. With 10x higher matrix tolerance 10x wider dynamic range and 10x better signal to noise ratio along with industry leading software and hardware suitable for analysis of nanoparticles single cells and for laser ablation you are certain to have the edge over the competition. A schematic of the la system is shown in figure 1.

Laser ablation inductively coupled plasma mass spectrometry la icp ms enables identification and comparison of physical evidence discriminating elemental and isotopic. The laser ablation icp ms system is used for micro sampling of solid material for trace element analysis. System was coupled to an agilent 7500s icp ms. It consists of a 213nm nd yag new wave pulsed solid state laser nwr213 coupled to an agilent 7900x icp quadrupole mass spectrometer.

Laser ablation icp ms is a widely used technique for the direct surface analysis of solid samples. La icp ms begins with a laser beam focused on the sample surface to generate fine particles a process known as laser ablation. Inductively coupled plasma mass spectrometry icp ms is a type of mass spectrometry that uses an inductively coupled plasma to ionize the sample. The agilent 7500 series excellent sensitivity high speed simultaneous detector and 9 orders dynamic range makes it perfectly suited to laser ablation analysis.

The agilent 7800 and 7900 single quadrupole icp ms and 8900 triple quadrupole icp ms icp qqq systems provide high sensitivity fast acquisition speed and 10 11 orders dynamic range. Connection to laser ablation la field flow fractionation fff and other sampling devices are also available and kits are available for the introduction of volatile organic solvents or samples that contain hf. Therefore 207 pb instead of 204 pb was chosen for the isochron chen et al 2014 yuan et al 2011 zhang et al 2014. Laser ablation la icp ms is used for the direct surface analysis of solid samples.

It atomizes the sample and creates atomic and small polyatomic ions which are then detected it is known and used for its ability to detect metals and several non metals in liquid samples at very low concentrations. In this study two calibration strategies matrix matching and non matrix matching were used for the quantitative analysis of high purity metals.
