With the ability to reduce mobile-phase consumables by up to 90%, the SRS Pro Solvent Recycling System (photo) redirects untainted mobile phase to the solvent reservoir during isocratic HPLC (high-performance liquid chromatography) operation. Powered directly from a USB connection, with easy plug-and-play operation, this system is ideal for any chromatography laboratory looking to conserve solvent use. Easy-to-use software enables simple configuration of the system parameters and includes online monitoring and audit-trail facilities. Through continuous monitoring of the HPLC detector output signal, the mobile phase is recycled to the solvent reservoir when the baseline is below a threshold value. When the threshold is exceeded, the eluent flow is redirected to waste, accounting for the transport time from the detector to the switching valve. — Thermo Fisher Scientific Inc., Milford, Mass.
