The development of MS started around 1920 where it was used to study the isotopic abundance of elements [1]. MS capabilities have increased greatly since 1920.
Webb1. Introduction. Optical fiber sensors based on Polymer Optical Fibers (POFs) have a number of advantages compared to sensors based on silica fibers, such as being flexible, durable, biocompatible, and biodegradable [1,2].These features make them particularly suitable for biosensors [3,4,5,6,7,8] and chemical sensors [9,10,11,12].Among these … WebbAboutTranscript. In the analytical technique of mass spectrometry, atoms or molecules are ionized using a high-energy electron beam and then separated based on their mass-to-charge ratios (m/z). The results are presented as a mass spectrum, which shows the relative abundances of the ions on the y-axis and their m/z ratios on the x-axis.
