ICP-MS Basics

• Mass range 6 Li to 238 U

• Mass discrimination types

• High resolution (e.g., magnetic sector) • Lower resolution (quadrupole)

• Resolution (R) • R = m / Δ m

• m = mass being measured • Δ m = mass difference between two resolved peaks

Mass Resolution

• Resolution (R) • R = m /Δ m

• m = mass being measured • Δ m = mass difference between two resolved peaks

• Quadrupole typical R = ~400-600 • Magnetic Sector R > 10,000
