The molecular ion represents the entire molecule in question, prior to any fragmentation. Each analyte molecule is given a charge of one, so the molecular ion m/z value represents the molecules total mass. Ionization, specifically electron impact (EI) ionization, is used to remove an electron f...
A method that analyzes mass spectra using a digital computer is disclosed. The method includes entering into a digital computer a data set obtained from mass spectra from a plurality of samples. Each sample is, or is to be assigned to a class within a class set having two or more classes...
Mass spectrometry (MS) is an analytical laboratory technique to separate the components of a sample by theirmassand electrical charge. The instrument used in MS is called mass spectrometer. It produces a mass spectrum that plots the mass-to-charge (m/z) ratio of compounds in a mixture. How ...
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 to this Questio...
Consider two approaches to writing an article. Both are legitimate: 1. There is a single key finding, a headline result, with everything else being a modification or elaboration of it. 2. There are many little findings, we’re seeing a broad spectrum of results. ...
Correcting your exposure is not difficult if you understand how to read a histogram. Especially since you can make adjustments as necessary based on what your histogram tells you. You can tweak the exposure by adjusting ISO, Shutter, or f/stop based on your lens and camera’s ability to ...
a valediction. In decades past, regards implied not only esteem but also affection; today it sits somewhat higher on the spectrum of formality. So, best regards means with my best wishes and esteem, or something to that effect. Today, thanks to concise email writing, these phrases have ...
To paraphrase Eric Beck, “At either end of the educational spectrum there lies a hacker class.” And we are not interested in hackers, evengreat hackers. We need those middle of the spectrum folks who are going to live in the suburbs, commute to our offices, and do a decent job for ...
Subpopulations of soluble, misfolded proteins can bypass chaperones within cells. The extent of this phenomenon and how it happens at the molecular level are unknown. Through a meta-analysis of the experimental literature we find that in all quantitative
Spectrometers work by splitting incoming light into its individual wavelengths. Traditional designs achieve this using slits that deflect different wavelengths at varying angles. The separated light rays are then directed toward a detector, where their intensity is measured to construct a spect...
