The DSA Analyzer is a handheld breathalyzer intended for the detection of COVID-19. The analyzer measures the exhaled breath for 30 seconds and results are available in 2 minutes.

How does it work?


The unit contains a set of carefully selected and configured nanosensors that record Volatile Organic Compounds (VOC) and other substances connected to the biomarkers to be identified in exhaled breath gas. The biomarker VOC’s are born in human metabolism and their known relation – the VOC profile – with a given disease forms the basis for the analysis.

The Analyzer communicates with an Artificial Intelligence based cloud algorithm to calculate how well the measured breathprint of the individual’s VOC profile matches with the known COVID-19 features. The results are available immediately.

The Analyzer and future development versions will be brought available for early detection of diseases such as lung and colon cancers and chronic obstructive pulmonary disease (COPD).
