Auto-Diagnostics and Recovery

In rare cases, air bubbles can form in the mobile phase and cause problems if inhaled into
the pump. The Nexera has the ability to monitor baseline changes and pressure
fluctuations to check for abnormalities.
When it detects an unusual fluctuation, it can automatically pause the analysis, purge
the flow path, and restart analysis once it has confirmed recovery to normal pressure.
