Applications of DART-MS

In the medical area, one study using DART has been applied to human breath. Diagnosis through online breath analysis was fonnd to be difficult due to the dispersion of the breath samples in open air. A confined DART ion source (cDART) was developed and this was tested on fonr standard compounds—ethanol, acetone, 2-hexanone, and limonene— with detection limits approaching 1 ppbv after calibration [188]. 

Other applications of DART inclnde forensics where differences in writing inks were identified [189] screening for trace explosives [190] pharmaceuticals [191] and chemical analysis [192-194] to name jnst afew of the many investigations.
