DART QDa with LiveID by Waters

The Direct Analysis in Real Time (DART) QDa with LiveID system targets application areas where rapid, real time fingerprinting is essential and where sample preparation is not necessary or desirable.

• Minimize sample preparation with direct analysis
• Classify samples with real time recognition
• Straightforward operation and data interpretation
• Go from analysis to decision making in seconds

Bringing the benefits of real time direct analysis to your laboratory

DART is a desorption APCI (atmospheric pressure chemical ionization) technique where heated, ionized gas is directed at a target between the DART interface and the QDa mass detector. It can ionize molecules from the surface of a solid, liquid or vapor  making it applicable to a broad range of applications. The speed of generating mass spectra with minimal or no sample preparation makes DART QDa an ideal tool within laboratories where rapid informed decisions are necessary.

Rapid, easy-to-interpret classification of samples

The LiveID software platform enables real-time classification of sampling using DART QDa. Information is provided to the user immediately at the time of analysis, enabling informed and instant decision making while removing doubt over sample identity. First, authentic or verified samples are used to create and validate a statistical model. The validated model can then be used with test samples and generate live classifications. The output is a simple to interpret yes/no answer.
