Direct Analysis in Real Time

Features

DART (Direct Analysis in Real Time) is a new ion source that can analyze samples with various states and shapes without any sample preparation.

JEOL, the pioneer of ambient ionization

DART was born in 2003 at the mass spectrometry applications laboratory of JEOL USA, Inc. Among a series of new ionization techniques, which were later termed “ambient ionization,” DART was the first to have been invented and the first to have been commercialized in 2005. It was introduced at the Pittsburgh Conference in February 2005 and awarded the Pittcon Editor’s Gold Award as one of the best new products of the year. It was also awarded for the R&D 100 Award in September of the same year.

Direct analysis without sample preparation

You can acquire high mass-resolution, accurate-mass spectra in real time by simply presenting samples of various shapes and states to the DART ion source without any sample preparation. DART can handle samples with arbitrary shapes or “dirty” sample that conventional analytical method cannot deal with.

AccuTOF LC-plus 4G + DART: the perfect combination

The DART was developed for the JEOL AccuTOF™ series of mass spectrometers. No additional interface is required between the DART and the AccuTOF™ LC-plus 4G due to a rugged, simple API interface and high-capacity vacuum pumping system. The combination is able to detect a wider range of polar and nonpolar compounds than any other DART MS system. With no additional interface, there is virtually no carryover from one analysis to another, even for “dirty” and “sticky” samples.
