Key Terms
Accelerator Mass Spectrometry (AMS)
Radiocarbon Dating Analysts specializing in Accelerator Mass Spectrometry (AMS) play a crucial role in accurately determining the age of archaeological, geological, and environmental samples by measuring isotopic ratios of carbon-14. Expertise in AMS technology enables analysts to detect rare isotopes at ultra-trace levels, significantly improving precision and reducing sample size requirements compared to traditional radiometric dating methods. Advanced data interpretation skills and familiarity with contamination prevention protocols ensure reliable results that contribute to research in paleoclimatology, anthropology, and conservation science.
Sample Pretreatment
Sample pretreatment in radiocarbon dating involves removing contaminants such as carbonates, humic acids, and modern carbon to ensure accurate age determination of organic materials. Techniques like acid-base-acid (ABA) treatment and solvent extraction are critical for preparing samples before combustion or graphitization. High-quality pretreatment directly improves the precision and reliability of radiocarbon measurements used in archaeology and geosciences.
Calibration Curve
A Radiocarbon Dating Analyst specializes in interpreting radiocarbon data by applying advanced calibration curves to convert raw radiocarbon years into accurate calendar dates. Expertise in utilizing the IntCal calibration curve ensures precise alignment of radiocarbon results with historical timelines, accounting for fluctuations in atmospheric C-14 levels over time. Proficiency in software tools like OxCal and CALIB enhances the reliability of age estimations essential for archaeology, geology, and paleoclimatology research.
