What is a mass spectrum ? Protein Identification using Mass Spectrometry What is a mass spectrum ? Half massBinz, Pierrealain
To accurately determine a spectrum for substances, a gaseous form of the substance must be subjected to light and a spectrum is created. So, when samples are loaded into spectrometers, the high temperature of the machine vaporizes the tiny sample and light is refracted accordingly to the composit...
A transmission optical spectrometer is used to measure the absorption (or reflectance/transmission/emission) of a sample in the near UV throughout the visible region of the spectrum. The spectrometer consists of a light source, a dispersion element, a sample chamber, and a detector. Broadband lig...

A telescope is a broad term that covers a range of instruments for investigating the electro-magnetic spectrum. For this article we will look at the more common instruments that beginners and amateurs may use to investigate the night sky. Optical telescopes collect and magnify visible light, typic...
This is not to say that this piece of mathematics was solely responsible for these developments; but, as I hope to explain here, it was certainly part of the research and development ecosystem in both academia and industry, spanning multiple STEM disciplines and supported by both private and ...
What is a Spectrogram?Analysis Author Jade Vande KampA spectrogram is a graph that displays the strength of a signal over time for a given frequency range. Using a color spectrum, it points to the frequencies where the signal’s energy is highest and shows the energy variation over time. ...
The concept of research and development is widely linked to innovation both in the corporate and government sectors. R&D allows a company to stay ahead of its competition. Without an R&D program, a company may not survive on its own and may have to rely on other ways to innovate such as ...
For example, primary sector companies are directly engaged in activities utilizing natural resources, such as mining and agriculture. On the other end of the spectrum, the tertiary and quaternary sectors, representing the services and knowledge-based economy, are engaged in activity that is not direc...
