Elemental Analysis I. X-rays, UV/visible line emission, UV/visible line absorption, Ions/mass spectrometry, and why titration, gravimetry, spectrophotometry and electrochemistry rarely are competitive in industrialized societies: parallelism, selectivity, and detection limits. II. Techniques available at HUS: ICP-mass spectrometry, atomic absorption, spectrophotometry/redox or complex chemistry. Also common: ICP-emission spectrometry. Vocabulary: inductively-coupled plasma III. What's the physics? A. n u /n l = g u /g l exp - Δ E/kT . At high enough temperature, ionization is significant. Then electrostatic fields can manipulate ions and allow mass selection and detection. B. Why mass spectrometry is done in vacuum: reduced probability of collision.
