Microanalytical Reference Materials and Accessories

Photo of laser standards.The USGS Microanalytical Reference Materials (MRMs) are designed for use in the quantitative analysis of geologic samples using direct solid sampling techniques such as Laser Ablation ICP-MS. Recommended and informational total element concentrations were obtained through international round robin analysis using both bulk and microanalytical data.

Samples are distributed in polished epoxy mounts and ready for immediate use. These MRMs are supplied as individual samples or as sets contained within a plastic holder. Accessories are also available which integrate the USGS MRM holder with standard sample chamber mounts for CETAC® and New Wave® laser ablation systems.
