The presence of lead in blood is the most incontrovertible evidence of absorption but hitherto the need for venepuncture has limited its determination in the supervision of industrial workers.

Acoustic absorption is a fundamental parameter in the evaluation and optimisation of noise control within various environments. Recent advances have improved our ability to characterise how materials ...

Flame Atomic Absorption Spectroscopy (FAAS) is a very popular analytical technique that has been employed by researchers for the elemental analysis of trace metals in a variety of samples. How does it ...

Atomic Absorption Spectroscopy (AAS) is a technique that deals with the absorption of electromagnetic radiation of free gaseous atoms at a specific wavelength. AAS allows the measurement of extremely ...

A never-before-seen image of individual oxygen atoms dissolved in water has been captured.

Allergies are the most common cause of asthma. The immune system over-reacts to harmless substances such as birch or grass pollen, for example, forming immunoglobulin E antibodies (IgE). Together with ...

TDLAS based system for water-vapor measurement through varying smoke obscuration. Pre- and post-suppression concentrations comparable except in metal structure. Highest temperature and water-vapor ...
