WebWe could type this into a calculator and get some number and then look that up on a periodic table of elements, or we could just try to estimate it. We can see that it's going to be close to 88 because that's where the highest percentage is. When we're taking the weighted average, we have the highest weight right over there. WebFeb 1, 2024 · The three main parts of a mass spectrometer are the ion source, the mass analyzer, and the detector. Step 1: Ionization The initial sample may be a solid, liquid, or gas. The sample is vaporized into a gas and then ionized by the ion source, usually by losing an electron to become a cation.
