Achieving Ultra-Sensitive Inductively Coupled Plasma – Mass Spectrometry (LA-ICP-MS) Analysis with the J200 LA Instrument: A Glass Sample Study Application Note · PlasmaQuant MS Elite
Introduction
Laser ablation (LA) is a direct solid sampling technique that uses a laser pulse to remove small amounts of mass (pg – fg scale) from a sample of interest. Combining LA with inductively coupled plasma – mass spectrometry (ICP-MS) offers very attractive technical benefits for the analysis of solid samples, which include little to no sample preparation, high precision measurements, and superior sensitivity (down to ppb levels) with respect to other atomic spectroscopy methods. LAICP-MS analysis also offers both elemental and isotopic information. Depending on the laser sampling method deployed, LA-ICP-MS can be used for traditional bulk analysis, as well as for spatially-resolved analysis such as elemental/isotopic mapping and depth profiling.
The following application describes the analysis of glass samples (NIST SRM, trace elements in glass) to determine the absolute mass that can be detected and the limits of detection (LODs) when interfacing an Analytik Jena PlasmaQuant® MS Elite ICP-MS and Applied Spectra Inc.’s J200 LA instrument.
