Laser Ablation Icp Ms Sample Preparation

Specialized sample introduction systems can be coupled to an icp ms including spark or laser ablation systems hydride generators and chromatography systems gc ic hplc and uplc systems.

Laser ablation icp ms sample preparation. 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. Typically samples are introduced into an icp ms by aspirating a solution of the sample. This process is time. Nwr266macro laser ablation platform is the ideal instrument for bulk analysis by icp oes or icp ms with its close to 1mm diameter spot size capability.

Geological rock and soil samples by x ray fluorescence and laser ablation icp ms. Submit a minimum of 8 grams powder or 30 grams whole rock. Nwr193 laser ablation platform is an arf excimer based laser ablation system designed for solid sampling of all materials transported and ionized by the icp. Standard reference materials and on different geological samples using laser ablation in conjunction with a high resolution inductively coupled plasma mass spectrometer.

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. Inductively coupled plasma mass spectrometry icp ms is a type of mass spectrometry that uses an inductively coupled plasma to ionize the sample. Samples may be submitted as powders or in bulk. All samples are analyzed as glass disks prepared by fusion of finely ground rock powders with lithium tetraborate.

For conventional icp ms analyses a portion of the sample would need to be dissolved using acids which imposes a considerable workload exposure to potential hazardous chemicals and risk of contamination. Laser ablation la icp ms is used for the direct surface analysis of solid samples. Schematic representation of the sample introduction in icp ms from jarvis and jarvis 1992. In these cases sample preparation protocols will vary depending on the sample introduction system being used.

Introduction to laser ablation icp ms for the analysis of forensic samples application note often liquid samples require little preparation but without a solid sampling accessory solid samples need to be dissolved. La icp ms begins with a laser beam focused on the sample surface to generate fine particles a process known as laser ablation.
