Laser-based Green and Efficient Sample Preparation Procurement for Geological Samples with Complex Matrices
Published 2023-10-01“…However, the small sample volume of laser ablation cannot represent the chemical composition of complex and inhomogeneous samples, resulting in poor analytical precision and accuracy, which hinders its application in whole-rock bulk analysis. It is critical to prepare complex whole-rock geological samples into homogeneous and stable sample targets.OBJECTIVESTo establish a green and efficient pretreatment technique for LA-ICP-MS whole rock analysis of complex geological samples.METHODSThe samples were first calcined at 1000-1100℃ to remove volatiles, pressed into pellets, and then melted by high-energy wide pulse width infrared laser irradiation to finally obtain a homogeneous and stable sample glass.RESULTSCompared with pressed powder pellets, the new sample preparation procurement improved the analytical precision of each element in marine sediments GBW07354 and GBW07356 by an average of 7.7 times and 3.9 times, respectively. …”
