Leak Management
The leak management consists of the leak sensor and the drainage system
(funnels, hoses, nozzles). The drainage system ensures that escaping liq-
uids flow into a waste bottle. When leaks are registered by the leak sen-
sor, the LED flashes red. Both the device and the data acquisition via
chromatography software are stopped.
