Questions and Answers

What are the principal differences between the particles?

The principal differences between the particles are their masses.

What are the effects of charged particles in electric and magnetic fields?

Charged particles, when subjected to electric or magnetic fields, experience deflection and/or acceleration. This phenomenon is utilized in mass spectrometers to separate and analyze various particles.

Describe the role of electric and magnetic fields in mass spectrometry.

Electric and magnetic fields play a crucial role in mass spectrometry by separating and detecting different ions based on their mass-to-charge ratio. Electric fields accelerate the ions, while magnetic fields deflect them based on their charge and velocity, allowing for their separation and identification. Signup and view all the answers

Study Notes

Mass Spectrometry

Mass spectrometry separates charged particles with different masses and measures their masses
This technique also measures the relative amounts of different particles
Atoms in substances contain protons (positive charge) and electrons (negative charge)
If an atom loses an electron, it gains a positive charge (X+), forming a positively charged particle
If an atom gains an electron, it gains a negative charge (X-), forming a negatively charged particle
Charged particles are affected by electric, electrostatic, and magnetic fields
The paths of charged particles are changed (deflected) by these fields
Early scientists used these phenomena to study atoms
