Atmospheric Solids Analysis Probe (ASAP)
Rapid Direct Analysis of Volatile and Semi-Volatile, Solid and Liquid Samples.
The Atmospheric Solids Analysis Probe* (ASAP) is a useful tool for the rapid direct analysis of volatile and semi-volatile, solid and liquid samples using atmospheric pressure ionization. The ASAP technique utilizes the heated nitrogen desolvation gas to vaporize the sample and a corona discharge for sample ionization. This allows low polarity compounds not amenable to ESI, APcI and APPI to be ionized with a high degree of sensitivity. Furthermore, complex mixtures can be analyzed without the need for any sample preparation
