AccuTOF™ DART® Product Brochure

Rapid, Accurate Open Air Analysis

Direct Analysis with Time-of-Flight MS

AccuTOF-DART® is the perfect union of a time-of-flight mass spectrometer and an open air ion source. The DART ion source fully utilizes the speed and accuracy of the AccuTOF for small molecule analysis, producing clean, reproducible, easy-to-interpret data.

Real Time Analysis

AccuTOF-DART has completely changed the field of mass spectrometry. Now you can immediately determine chemical composition of knowns and unknowns, and produce high-resolution, accurate mass spectra by simply placing a sample, in its native form, between the DART ion source and the AccuTOF mass spectrometer inlet.

Wide Analytical Range

No interface is required between the DART and the MS, therefore the AccuTOF-DART is able to detect a wider range of polar and nonpolar compounds than any other ambient mass spec system.

Award-winning Technology

JEOL introduced the DART ion source in 2005, and the technology quickly gained recognition, winning both the Pittcon Editor’s Gold Award and the R&D 100 Award. Since that time nearly 400 papers have been published by chemists using the AccuTOF-DART. The introduction of DART made it possible for the first time to carry out atmospheric pressure ionization for analysis of samples in open air.
