Raman spectrometry

Raman spectrometry

Raman spectroscopy provides important information about materials. When laser light hit a sample, a small percentage of the scattered light may be shifted in frequency. The frequency shift of the Raman scattered light is directly related to the properties of the sample material. A Raman spectrum provides a “fingerprint” that is unique to the material. Raman spectroscopy is employed in many applications including mineralogy, pharmacology, corrosion studies, analysis of semiconductors and catalysts, in situ measurements on biological systems, and even single molecule detection.

EDXRF explained or how to do the chemical analysis.

Energy Dispersive X-ray Fluorescence or EDXRF is known to scientist at least 50 years. It became very favorable tool to measure chemical compositions about 30 years ago. This is due to ability to produce by many companies a portable X-ray source and small Si-pin detectors.

Red light fighting disease and helping healing faster.

It is not a myth anymore. Many people start using red and infra-red lights to fight different health problems. In this article we will try to describe in general terms what does science and medical world know and uses for healing in terms of light.
