Packet 8: Bonus 8

In addition to developing the first chemical laser, George Pimentel pioneered a technique that uses these components to isolate species of interest for spectroscopic analysis. For 10 points each:
[10m] Sinapinic acid is often used as what type of component during “soft” ionization protocols like MALDI? Generally, this term is used to denote the components of a sample other than the analyte of interest.
ANSWER: matrix [accept matrix isolation or matrix-assisted laser desorption/ionization]
[10e] Soft ionization protocols like MALDI and ESI are used to prepare samples for this technique, which analyzes molecules based on their m/z ratio.
ANSWER: mass spectrometry [or MS]
[10h] In this other soft ionization technique, samples are mixed into a liquid matrix then subjected to high energy beams of argon or xenon to generate ions of the analyte of interest.
ANSWER: fast atom bombardment [or FAB]
