mass spec
-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.
The Urban Dictionary Mug
I love it! Thanks! So
Great present for a retiring colleague with custom saying she's known for!
Loved this mug! So unique and you can edit the text to add something unique.
I gave it to my friend who took money from me and never returned.
I love the fact that I was able to customize my name since I've never been able to find anything with my name. The only downside is it's smaller than I thought it would be (I guess I didn't pay much attention to that), wish it was bigger, only about 10 oz total.
It's simply awesome; and plus, the word means a lot.
Really fast and looks great! Took a chance on Christmas gift and it was a success!
Awesome mug feels really nice good weight and color although I think the shade could be a little brighter when it comes to the highlighter yellow, I am still pleased with the outcome and the fact that a whole passage was so neatly printed onto the product, very pleased with the packaging too! That made it so easy to wrap just in time for Christmas. Who knew!!
okay so the mug was mid but when you have a genz meme and give it to one of the most serious people you know then it's pretty funny
Nice mug, great feel‼️
Perfect!
Good quality ceramic cup! Worth the novelty price!
Perfect gift for my gf
Looks great! Came quick
Gave it to my nerd brother. He used it consume liquid
Love it
as a fan of non-Z-generation-UD (since 2000 more or less) , especially of old-school definitions ("phat!") (as Nick, the more time passes by, the more I reach my inner age = 75 XD) , I totally appreciated the delivery in time for Christmas! (whispering) Perhaps printing quality in the Spain printing company is not as good as in the US, but - hey! - I got it before Christmas as a gift for my thank-God-non-Gen-Z-sister! ;) hugs from the eighties, and from Italy, and thanks!

This is SO cool. Morning coffee will always memorialize my new addition to the English lexicon.
Too inappropriate
Item came at appropriate time in good condition.
