Leak Management
The leak management consists of the leak sensor and the drainage system
(funnels, hoses, nozzles). The drainage system ensures that escaping liquids
flow into a waste bottle. When leaks are registered by the leak sensor, the
LED flashes red. Both the device and the data acquisition via chromatogra-
phy software are stopped.
Prerequisite The front cover has been removed.
