The GX-274 Aspec is a four-probe instrument capable of parallel solid phase extraction (SPE) processing of samples to increase both throughput and the efficiency of SPE cartridge-based applications.
Based on positive pressure elution, this instrument processes up to four samples in a single step with a sealing cap technology, where each cartridge is sealed, run and monitored individually.
The two 406 dual syringe pumps allow the user to transfer liquids, process up to four samples in parallel, and to monitor pressure on each fluid path individually.
Fundamental to Gilson's automated SPE system is the mobile rack and positive pressure technology.
This technology allows the user to automate the entire SPE and liquid handling processes from the initial condition to the final transfer.
Gilson's SPE instrumentation utilises positive pressure to ensure more reproducible flow rates, more reproducible recoveries, less sample-to-sample contamination, and higher precision.
All Gilson SPE instruments are controlled via Trilution LH software.
