Abstract: The DART ion source provides a combination of thermal desorption and predominantly atmospheric pressure chemical ionization (APCI) to directly ionise samples in their natural states. Taking advantage of the speed of DART analysis, complex samples can be fingerprinted in a few seconds without chromatography and with little or no sample preparation. The DART ionisation technique is amenable to solid, liquid and gaseous samples and a number of sample holders allow the user to automatically present their samples to the ionisation region in a reproducible manner lending itself also to quantitative analyses. Applications of DART ionisation range from: food adulteration and contamination issues, organic synthesis reaction monitoring, screening drugs of abuse, nutraceutical characterisation, art preservation/history and many more to explore.
