ASAP Atmospheric Solid Analysis Probe
Press Release (IonSense) IonSense Expands Product Line with ASAP Open-Air Ionization Source. Will be sold to MS-systems from most instrument vendors. ASAP works on API sources like a solid probe.
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 to other direct API techniques such as DART™ or DAPCI. In the ASAP method, vaporization of the sample occurs when it is exposed to a hot nitrogen desolvation gas from an ESI or APCI probe supplied with the instrument. The ASAP probe does not interfer with ESI or APCI operation, making switching between methods nearly instantaneous. This technique 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™, and others.
Benefits Low cost Does not interfer 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

DART is an Ion Source that permits analysis of samples without any pre-treatment. It can be mounted on a TOF-instrument or OrbiTrap for identification of unknown samples or Quadrupoles for rapid Target Analysis.
