Detection of Oleocanthal in Freshly Pressed Exra-Virgin Olive Oil
We used DART to rapidly examine cooking oils for the presence of the compound oleocanthal, that has properties similar to the common anti-inflammatory drug, ibuprofen.

|
Detection of Unstable Compound Released by Chopped Chives
The lachrymator released by chopped onions is reactive and unstable and is
therefore difficult to analyze by conventional mass spectrometry techniques. However, DART® was easily able to detect propanethial S-oxide when a freshly cut chive bulb was placed in front of the mass spectrometer.

Rapid Detection of Fungicide in Orange Peel
A small piece of orange peel (a few square millimeters in size) from a Florida orange was placed in the DART® sampling region. Compounds present in the
peel were detected within seconds.

Using Solid Phase Microextraction with AccuTOF-DART® for Fragrance Analysis
In this work, the Direct Analysis in Real Time (DART®) heated gas stream is used to desorb and directly introduce a SPME sample into a high-resolution mass spectrometer. This methodology produces comparable information to the traditional GC-MS technique but streamlines the results into only a few seconds of analysis time.
