DART stands for Direct Analysis in Real Time. It is a new ionization for rapid, non-contact surface sampling of compounds. Operating at ambient pressure with the sample at ground potential, the source enables near instantaneous determination of sample composition by using mass spectrometry. Electronic or vibronic excited-state species generated in the source interact with reagent molecules and polar or non-polar analyte present near the inlet of the mass spectrometer.
The DART source mounts on the front of your Mass Spectrometer using our Vapur® interface. Liquid samples can be ionized instantly by coating the outside of a DIP-it tip with your solution and placing it in front of the DART gas stream. For analysis of solids and TLC plates, choose our new DART-ET, with a wider sampling area and tilting capability.
