Introducing ReSolve · Antech Ireland · 1 minute 7 seconds. Recovery and reuse depend on the method.

THE RECOVERY PRINCIPLE

Recover the baseline.
Divert the peaks.

ReSolve uses the detector signal to control a valve after the detector. Selected flow returns for reuse; detected peak fractions go to waste.

Between peaks: return flow

Eligible baseline flow returns to the reservoir within the approved reuse method.

Peak detected: divert to waste

Peak fractions go to waste, including the configured timing margin.

Detector-to-valve delay and peak margins are configured for the method. ReSolve routes the liquid; it does not purify it.

THE EVERYDAY LABORATORY BENEFIT

Less fresh solvent.
Less liquid waste.

Make suitable repeated methods work harder for your laboratory.

01

More use from each preparation

Return eligible mobile phase to the working reservoir and reduce the fresh volume needed for suitable repeated methods.

02

Less liquid sent to disposal

Separate peak fractions from recoverable flow and measure the reduction in waste across the complete workflow.

03

Fewer bottle changes

Extend the use of a suitable preparation, reducing reservoir refills and waste-bottle handling.

Include top-ups, purging, cleaning, replacement and eventual disposal in your assessment. Recovery percentage and total cost saving are different measures.

Recovery measured alongside analytical performance.

Two sequences each contained 96 injections; the second used mobile phase recovered from the first. The study reported comparable observed chromatographic metrics with fresh and recovered starting mobile phase.

Paracetamol/ibuprofen method; buffer, acetonitrile and methanol at 75:24.5:0.5 v/v/v. PMBrc / SETU, final report Rev 4.0, 22 July 2026. Results apply to the tested sequences; they do not establish a universal recovery rate, formal statistical equivalence or unlimited reuse.

MATCH THE PRODUCT TO THE METHOD

Plan a practical installation.

Start with a suitable isocratic method, the actual detector output and a representative chromatogram.

Which methods should we evaluate first?

Prioritise repeated isocratic methods with a stable mobile phase and useful baseline intervals. Review the full sample matrix, detector response and permitted reuse period. The study does not establish suitability for gradient HPLC or SFC.

What should we send Antech?

Tell us your HPLC system and detector, the mobile-phase composition and flow rate, your sample matrix, a representative chromatogram and the number of runs you perform. We will help you plan an evaluation for your workflow.
