Webinar: Matrix effects and mineral characterization on LG-SIMS

Tuesday, February 10, 2026

Join us for a special webinar celebrating the International Day of Women and Girls in Science, presented by Laure Martin (UWA), who exploring one of the most critical challenges in Large Geometry SIMS (LG-SIMS) quantitative analysis: the matrix effect.

During this session, Laure Martin will explain what matrix effects are, where they originate, and why they represent a major source of uncertainty in SIMS‑based quantification. She will illustrate these phenomena using examples from our laboratories alongside established findings from scientific literature, highlighting the biases, intensity variations, and characteristic trends that can arise during analysis.

The webinar will conclude with practical recommendations designed to help participants better manage matrix effects in their daily analytical workflows. These actionable strategies aim to improve quantification reliability and enhance the robustness of LG‑SIMS data.

📅
February 26, 2026 - 11 AM CET (Paris) / 16 PM AWST (Perth)


⭐ Key learnings will include:

  • Understanding what “matrix effects” means and how it originates.
  • Recognizing how matrix effects can introduce bias and produce systematic trends in SIMS measurements.
  • Interpreting real world examples that illustrate the extent and variability of matrix effects.
  • Identifying analytical situations where matrix effects can significantly compromise quantification.
  • Applying practical advice and mitigation strategies to reduce the impact of matrix effects in LG SIMS workflows.


🎙️ About the speaker:

Laure Martin leads the SIMS platform at The University of Western Australia, which includes a CAMECA IMS 1280 and a CAMECA NanoSIMS-HR. She obtained her PhD in Metamorphic Petrology and Geochemistry at the CRPG laboratory in Nancy (France) and has about 20 years of experience in LG-SIMS applied to stable and radiogenic isotope geochemistry. Her work combines SIMS analysis with detailed petrology to investigate fluid–rock interactions in a wide range of geological contexts. After focusing on metamorphic terranes and processes such as exhumation and subduction, her recent work at CMCA has expanded to ore deposits (Ni–Cu sulfides, orogenic gold, porphyry systems) and in more superficial environments including sedimentary basins and geothermal systems.
