X-Ray Fluorescence (XRF) Spectrometer

X-Ray Fluorescence (XRF) Spectrometer X-ray fluorescence (XRF) is used to detect and measure the concentration of elements in substances. Fluorescence is the phenomena of absorbing incoming radiation and reradiating it as lower-energy radiation. X-rays are part of the electromagnetic spectrum with energies ranging from 0.1 keV to 100 keV (Fig 1a). X-rays are produced by …

Greenhouse Gases and Climate Change

Greenhouse Gases and Climate Change Gases which trap heat in the atmosphere are called greenhouse gases. Several chemical compounds in the atmosphere act as greenhouse gases. These gases allow sunlight (shortwave radiation) to freely pass through the atmosphere and heat the land and oceans. Greenhouse gases occur naturally and allow the life to survive on …
