Smart Saver - USB Solvent Recycler

Operational Principle:

SmartSaver continuously monitors output signal of the chromatographic detector. Analog-to-digital converter produces digital data for further evaluation in built-in processor. If the input signal level exceeds the pre-set value (threshold), SmartSaver redirects the flow to the waste, respecting the transport time from detector to the switching valve. When signal goes down SmartSaver is waiting for transport delay again and then switch the mobile phase back to the reservoir. Auto sampler injection marker connected to the SmartSaver may ensure the zeroing of signal input at the moment of injection.
