Overview of MC-ICP-MS Facilities at MURR

Prepared by Virginie Renson, University of Missouri Archaeometry Laboratory

The MURR Archaeometry Laboratory recently acquired a Nu Plasma II multi-collector inductively coupled mass spectrometer with the assistance of a major research instrumentation grant from the National Science Foundation (#BCS-0922374). Multi-collector ICP-MS instruments allow measurement of isotopic ratios with high precision and reproducibility, and they additionally provide the capability of processing large batches of samples in a relatively short amount of time. Isotopic analyses have long been successfully applied in archaeometric studies on various types of artifacts. This approach is now being integrated into projects involving the other analytical methods already available at MURR.

Several ongoing projects in the Archaeometry Laboratory will focus on studies of isotopes in ceramics, clays, bones and teeth. These projects include:

A laboratory room at MURR has been entirely renovated, cleaned, and equipped to provide the clean environment required for sample preparation for isotopic analysis. This new equipment includes custom-designed boxes with filtered air (HEPA), a laminar air flow cabinet, polypropylene tables, corrosion-resistant lab hot plates suitable for Class 1, analytical balance and anti-static device, ultra-sonic bath, a micro-centrifuge, and inert and acid resistant material.

This laboratory is now operating as an ISO 4 to ISO 5 class room according to the ISO 14644-1 classification system. Procedures for preparation of various types of samples (ceramics, clays, bones and teeth) as well as procedures for lead and strontium separation are being developed. They will be followed in the near future by procedures for other types of artifacts and isotopic systems

Research performed by the Archaeometry Laboratory at MURR after August 2014 is supported by the National Science Foundation under our current grant number 1415403. Earlier research was supported by several NSF grants including the following: 1110793, 8801707, 9102016, 9503035, 9802366, 9977237, 0102325, 0405042, 0504015, 0802757, 0922374, and 0802757.
