Direct analysis in real time mass spectrometry (DART-MS) has become an established
technique for rapid mass spectral analysis of a large variety of samples. DART-MS is …

Ambient ionization mass spectrometry allows the rapid analysis of samples or objects in
their native state in the open environment with no prior preparation. Over the past six years …

Positive ions in the direct analysis in real time (DART) ion source are commonly formed by
proton transfer. However, the DART source is similar to atmospheric pressure …

The number and type of atmospheric pressure techniques suitable for sampling analytes
from surfaces, forming ions from these analytes, and subsequently transporting these ions …

Ambient ionization techniques enable the interrogation of a variety of samples in their native
state by mass spectrometry, and are rapidly advancing all fields where screening for the …

Direct analysis in real time (DART) is an ion source that permits rapid mass spectrometric
