Plasma Diagnostics and Optical Emission Spectroscopy

Posted on: January 28th, 2020

Plasma is an ionized gas under pressure and subjected to intense heating or electromagnetic fields to the point that electrons and positive ions are unbound. Plasma is one of the four fundamental states of matter, but it does not exist on Earth naturally and must be generated by applying heat and pressure. What makes plasma…

Spectra: Plasma Measurements

Posted on: January 23rd, 2020

Background/Applications: Optical Emission Spectroscopy, often referred to as OES, is a widely used analytical method to determine the elemental composition of a broad range of metals. Types of samples which can be tested using OES include samples from the melt in primary and secondary metal production, and in the metals processing industry. OES commonly uses…

Spectra: Season of Lights

Posted on: December 19th, 2019

Conducted by: David Ademe, Avantes Inc. Theme: LED’s/Irradiance Background/Applications: Spectral irradiance is the irradiance of a surface per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. The two forms have different dimensions: spectral irradiance of a frequency spectrum is measured in watts per square…

Spectroscopy in Sustainable Soil Management

Posted on: November 21st, 2019

Agricultural research of today goes into feeding the world’s population tomorrow. Year after year, farmers try to produce more food out of the same resources, and rapidly changing climate conditions only heighten the pressure on the world’s food supply. Changing weather patterns means droughts deepen, floods are more frequent, extremes of heat and cold swing…
