mass spec Mug
-Slang for Mass spectrometry. NOT mass spectroscopy… spectroscopy is NOT the same as spectrometry. Spectroscopy uses light… this spectrometry does not… -A common tool amongst chemists of all varieties since it can distinguish between molecules based on very small differences in mass. In principal it works by ionizing a molecule with some sort of ionization source (electron impact, electrospray ionization, chemical ionization, MALDI, ect…), the charged molecule is then accelerated through a mass selector, which can vary in form from a magnetic sector to a quadrupole, to a time of flight (TOF) selector. After selection, the molecule is directed to a detector where it is measured or directed to another portion of the apparatus for further experimentation. Mass spectrometry has been coupled with many separation methods such as HPLC, GC, and CE to yield quantitative information, while tools such as ICR has been developed for studies of reaction dynamics. Many experiments have been devised to measure very low concentrations of analyte since the sensitivity and signal to noise are so high. Also, the resolution of many spectrometers is quite good, allowing for molecules of similar mass to be distinguished. Organic chemists tend to use it for structure elucidation since a pattern of fragments can be used to piece together the structure when combined with other methods such as NMR and FTIR.

This mug has made me so happy. This is more than I could have ever wanted in life.
My friend loved it.!!

War. War Never Changes. War, war never changes. In the year 1945, my great-great grandfather, serving in the army, wondered when he get to go home to his wife and the son he never see. He got his wish, when the U.S. ended WWII by dropping an atomic cloud on Hiroshima and Nagasaki. The world awaited Armageddon, instead, something miraculous happened. We began to use atomic energy as a nearly limitless source of power. People enjoyed luxury once thought in the realm of science fiction. Domestic robots, fusion powered cars, portable computers. Then, in the 21st century, people awoke from the American dream. Years of consumption led to the shortages of every major resource. The entire world unraveled. Peace became a distant memory. It is now the year 2077, and we stand on the brink of total war, and I am afraid, for myself, for my wife, for my infant son, because if my time in the army taught me one thing; is that war, war never changes.
Excellent satire - didn't see comments to that end, so find it hard to fathom if most readers, in turn, didn't laugh out loud, and say so. But apparently not.
I am gonna buy it and give it to my nine year old brother
Super Funny Mug 😂
best mug ever spittin nothin but fax
i fucking hate your mugs and shirts
