The Thermo Scientific SRS Pro solvent recycling system re-uses solvent and reduces mobile phase consumption by up to 90%. It redirects untainted mobile phase to the solvent reservoir during isocratic HPLC operation.
Powered directly from a USB connection, with easy "plug and play" operation, the company says the system is ideal for any chromatography laboratory looking to conserve solvent use.
The SRS Pro's easy-to-use software enables simple configuration of the system parameters and includes on-line monitoring as well as audit trail facilities.
Through the continuous monitoring of the chromatographic detector output signal, the mobile phase is recycled to the solvent reservoir when the baseline is below a threshold value. If this value is exceeded, the eluent flow is redirected to waste, accounting for the transport time from the detector to the switching valve. When the signal returns below the threshold, the mobile phase is switched back to the reservoir.
Additionally, the SRS Pro is designed to recycle the mobile phase only when switched on. In case of a power failure, the valve is automatically put in the waste position and the mobile phase reservoir remains uncontaminated.
