10K Mass spectrometry is a substance from a crime scene that is analyzed by a mass spectrometer in order to find the molecular makeup. Explore how mass spectrometry can be used to identify all kinds of evidence such as cloths, glass, dyes, metals, and even human tissue. Related...
Relative ion current (signal) is plotted versus m/z producing a mass spectrum. Small molecules typically exhibit only a single charge: the m/z is therefore some mass (m) over 1. The ‘1' being a proton added in the ionization process [represented M+H+ or M-H- if formed ...

You can use it to measure the absorption spectrum of the photovoltaic material and compare this to the incident radiation. Mass Spectrometers Mass spectrometers produce spectra which show intensity as a function of mass-to-charge ratio. This is done by ionising the sample, supplying the ions with...
Let us assume an analytical technique which involves the identification of the chemical substances by sorting gaseous ions in the electrical and magnetic field according to their mass to charge ratios. Such a technique is said to be mass spectrometry....
Near Infrared (NIR) Spectroscopy is an analytical technique used across a wide range of sectors and industries. Click to read more...
In the broadest sense a spectrometer is any instrument that is used to measure the variation of a physical characteristic over a given range; i.e. a spectrum. This could be a mass-to-charge ratio spectrum in the case of a mass spectrometer, the variation of nuclear resonant frequencies in...
What is RFI? The term, which is an acronym for radio frequency interference, refers to noise that falls on the radio frequency spectrum within the electromagnetic frequency spectrum. Meanwhile, EMI refers to any frequency of electromagnetic noise. In other words, RFI is a subset of EMI and inc...
In 1995, building on earlier work by Bourgain, Wolff famously obtained (1) with using what is now known as the “Wolff hairbrush argument”, based on considering the size of a “hairbrush” – the union of all the tubes that pass through a single tube (the hairbrush “stem”) in ...
