Introduction to Mass Spectrometry (MS) A mass spectrometer produces a spectrum of masses based on the structure of a molecule. The x-axis of a mass spectrum represents the masses of ions produced (m/z) The y-axis represents the relative abundance of each ion produced

Mass (amu). x. Relative abundance (% as a decimal) . Calculating Average Mass. Atomic mass is the average of all the naturally isotopes of that element. Copper = 63.546 amu. Cu. Cu. Copper-63. 62.93 amu. x. 0.692 . = 43.54756 amu . +. Copper-65. 64.93 amu. x. 0.308 .

Part 3: Biodiversity. The Ecosystem Sustainer. The BIG Problem. The big problem with invasive species are their impact on biodiversity . Any kind of pollution inherently reduces biodiversity. However, invasive species are especially good at this.

The “Zen” of tea-cups. Long long ago, a scholar wanted to learn about Zen from a learned master. The learned master sat him down, and started pouring him a cup of tea……. But he poured and poured until the tea overflowed….. And he still continued pouring…….
