Note: All mass spectrometers that you will come across if you are doing a course for 16 - 18 year olds work with positive ions. Even if a few atoms in a sample of chlorine, for example, captured an electron instead of losing one, the negative ions formed wouldn't get all the way through the ordinary mass … ear clogged for 3 daysWeb4 de mai. de 2024 · The vertical axis represents the relative intensity or signal of the ions detected in the mass spectrometer, while the horizontal axis represents their m/z ratio (the mass divided by charge number). The strongest peak will therefore have a relative intensity of 100. Pentane has the chemical formula C 5 H 12. css border-image fill
