ASAP® Probe

ASAP on Q Tof

Atmospheric Solids Analysis Probe (ASAP®) mass spectrometry allows direct analysis of samples using an atmospheric pressure ionization (API) source found on Liquid Chromatography Mass Spctrometry (LCMS) instruments. The ASAP® probe permits fast analysis of solid, liquid, tissue, or material (e.g. polymer) samples. ASAP® is a low cost alternative ionization method that is especially useful on commercial high end API mass spectrometers which have the capability of accurate mass and mass-selected fragmentation, such as a Bruker Qh-FTMS™, Jeol AccuTOF™, Thermo Ortitrap™, or Waters Synapt HDMS™.


  • Low cost <$10K
  • Does not interfere with normal source operations on most instruments
  • Fast direct analysis
  • Compatible with ESI/APCI operations (No source change required)
  • Enclosed ion source for safety (vapors are contained inside the source)
  • No sample prep required, and solids as well as liquids can be analyzed
  • Low picogram sensitivity
  • Ideal for high resolution instruments
  • Good substitute for EI/CI solids probe analysis
  • Analyze LC fractions in seconds
