This Solvent Recycler saves up to 90% of mobile phase by redirection of the pure solvent to the solvent reservoir during the isocratic HPLC. The stand alone device is powered by 5 V DC from power adapter or from computer USB port. Working parameters (Threshold and Delay) are easily set on the display using a membrane keyboard.
Watrex: Watrex SPR-200 Solvent saver - INputs
The SPR-220™ Solvent Recycler continuously monitors the output signal of the chromatography detector and displays its current value on the built-in display. A highresolution analog-to-digital converter provides data for further evaluation in the built-in processor. If the input signal level exceeds a preset value (Threshold), the SPR-200 will redirect the flow to the waste.
When the signal drops, the solvent recycler waits for the transport delay and then switches the mobile phase back to the reservoir. An autosampler injection marker connected to the SPR-200 ZERO input can be used to zero the input signal at the time of injection.
