Area of Science:

  • Analytical Chemistry
  • Materials Science
  • Environmental Science

Background:

  • Total Reflection X-ray Fluorescence (TXRF) is a powerful elemental analysis technique.
  • Existing TXRF instruments can be large, power-intensive, or have limited efficiency.
  • Accurate elemental analysis of biological samples, like marine mollusc teeth, is crucial for environmental monitoring.

Purpose of the Study:

  • To present a novel, compact, and efficient Total Reflection X-ray Fluorescence (TXRF) instrument.
  • To evaluate the detection limits of the developed TXRF system.
  • To demonstrate the quantitative analysis capabilities of the TXRF system using marine mollusc teeth.

Main Methods:

  • Development of a short-path, high-efficiency, low-power, and small-volume TXRF instrument.
