We possess laser ablation analytical capabilities. These allow for elemental and isotopic analyses to be performed directly on solid samples and samples of irregular size and shape, i.e. in-situ analysis.
In-situ analysis includes the following major advantages:
- Sample preservation: minimally invasive method provides high-data quality while limiting loss or destruction of sample material.
- Spatial resolution: probing of sample material occurs in the micron range
- Time-resolved analysis: a record of temporal variation can be determined within a specimen.
PCIGR has two excimer laser ablation systems that are connected to various inductively coupled plasma mass spectrometers (ICP-MS) for a wide variety of research applications. For simultaneous trace element concentration and isotopic analyses, we offer laser ablation split-stream capabilities.
In-situ Capabilities
PCIGR can process and analyze the following types of sample materials* via in-situ ICP-MS:
- Rocks and minerals
- Drill cores
- Thin and thick rock sections
- Microscope slides and thin sections
- Archaeological and modern bones and teeth
- Lithic archaeological materials
- Advanced manufacturing materials
* Please note that PCIGR is not equipped to accept radioactive materials.
For questions about in-situ and microanalytical capabilities at PCIGR, contact Dr. Corey Wall and Dr. Marg Amini.
Please do not submit raw or prepared samples without first speaking to us. Thank you.
