Laser Ablation (LA)-ICP-MS for Production Control of Nickel Alloys Application
ثبت نشده
چکیده
Nickel alloys are used extensively across a wide range of industries, often in components which are required to perform critical functions under arduous operating conditions. As a result, the physical, chemical, and mechanical properties of such alloys must be well understood and the levels of trace metal contaminants, which may have a profound effect on these properties, must be strictly controlled. IncoTest (a business division of Special Metals Wiggin Ltd.) evaluated Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) to monitor and control a wider range of trace elements at lower levels than can be achieved on traditional instrumentation (X-ray Fluorescence and Optical Emission Spectrophotometry). Comparison data obtained using the different techniques is presented, indicating that in all cases, acceptable limits of detection, accuracy, recovery, and long-term stability were obtained using the LA-ICP-MS method.

Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS): comparison of different internal standardization methods using laser-induced plasma (LIP) emission and LA-ICP-MS signals.
The source of signal variations that governs the analytical performance of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was investigated in this study. In order to specify the source of signal variations of LA-ICP-MS, laser-induced plasma (LIP) Fe emission, LA-ICP-MS Fe+ and LA-ICP-MS Ni+ signals were used as internal standards for the determination of trace elements ...
متن کاملThe influence of laser pulse duration and energy on ICP-MS signal intensity, elemental fractionation, and particle size distribution in NIR fs-LA-ICP-MS.
Laser parameters, typically wavelength, pulse width, irradiance, repetition rate, and pulse energy, are critical parameters which influence the laser ablation process and thereby influence the LA-ICP-MS signal. In recent times, femtosecond laser ablation has gained popularity owing to the reduction in fractionation related issues and improved analytical performance which can provide matrix-inde...
