Introduction
DART™ (Direct Analysis in Real Time) is a revolutionary ion source that allows for the rapid analysis of samples in various states and shapes without any sample preparation. This technology provides high-mass resolution and accurate-mass spectra in real time. DART™ is designed to perform optimally with JEOL’s AccuTOF™ series of mass spectrometers.
Product Overview
Developed by JEOL, DART™ was the first ambient ionization technique to be commercialized. It enables users to analyze samples such as paper, food, biological fluids, and even human skin directly by simply presenting them to the ion source. DART™ eliminates the need for time-consuming sample preparation procedures, making it an ideal tool for rapid screening and on-the-spot analysis. When combined with the AccuTOF™ LC-Express, it forms a powerful system for detecting a wide range of polar and nonpolar compounds.
Key Features

FAQ
1. What is DART™?
DART™ stands for Direct Analysis in Real Time. It is an ionization technique that allows for the direct analysis of samples in open air without prior preparation.
2. What types of samples can DART™ analyze?
DART™ can analyze almost anything, including liquids, powders, tablets, and solid surfaces like paper, fabric, food, and even human skin.
3. How does DART™ work?
It uses a stream of gas (usually Helium) containing excited-state atoms to interact with the sample and atmospheric gases, generating ions from the analyte for mass spectrometric analysis.
4. Do I need to prepare samples before using DART™?
No, one of the biggest advantages of DART™ is the ability to perform direct analysis without any sample preparation steps like dissolving or extraction.
5. Which instruments is DART™ compatible with?
DART™ was specifically developed for JEOL’s AccuTOF™ series of mass spectrometers and provides the best performance when combined with the AccuTOF™ LC-Express.
Conclusion
