Here is a summary of the NIST article on Th-Ar hollow cathode lamps and line lists:
The National Institute of Standards and Technology (NIST) has published a comprehensive study on the spectral characteristics of thallium-argon (Th-Ar) hollow cathode lamps. These lamps are commonly used as light sources in atomic absorption spectroscopy (AAS) for elemental analysis.
The study provides detailed information on the emission spectrum of Th-Ar lamps, including:
– Wavelengths of 160 atomic absorption lines of thallium
– Line positions with an accuracy of 0.0001 cm⁻¹
– Line intensities with an uncertainty of 2-3%
– Line broadening parameters
The research team used advanced techniques to measure and analyze the spectral lines, including high-resolution Fourier transform spectroscopy and quantum chemistry calculations. The resulting line lists will help improve the accuracy and reliability of AAS measurements.
The study is expected to have a significant impact on various fields that rely on AAS, such as environmental monitoring, food safety, and industrial quality control. It will enable more precise and reliable elemental analysis, leading to better decision-making and problem-solving in these areas.
The research findings are published in the Journal of Physical and Chemical Reference Data, providing a valuable resource for the scientific community. The study demonstrates NIST’s commitment to advancing measurement science and supporting the development of accurate and reliable analytical techniques.
