I would have spent an hour deliberately guessing that Russian accent wrong, just so I could have heard it more LoL. This module focuses on the effects of isotopes on mass spectra. It also addresses practical applications of isotope measurement using a mass spectrometer. Dungeon monitor The ability of a mass spectrometer to distinguish different isotopes is one of the reasons why mass spectrometry is such a powerful technique. The presence of isotopes — a presence that is ubiquitous in nature — gives each fragment a characteristic series of peaks with different intensities. These intensities can be predicted based on the abundance of each isotope in nature, and the relative peak heights can also be used to assist in the deduction of the empirical formula of the molecule being analyzed. Almost all elements have a variety of naturally occurring isotopes — some notable exceptions are fluorine, phosphorous, sodium, and iodine. For example, Carbon has 6 protons.

These harsher methods often shatter the very proteins they are trying to measure. Mass spectrometry, though, doesn't shatter the proteins, and provides useful insights into the life sciences.

Industries, governments, and regulatory bodies need efficient ways to test the purity of our water, the cleanliness of our air, the content of our soil, and the quality of our food. Mass spectrometry is one of the most reliable methods for assessing whether or not a part of the environment is being contaminated by chemicals, pharmaceuticals, naturally occurring organics such as algal toxins, or pesticides. An investigation by the Associated Press has shown that the a wide range of pharmaceutical products including antibiotics, mood stabilizers, anti-convulsants, and sex hormones have been found in the drinking water supplies of about 41 million Americans.
