GL Sciences Automated SPE Elution Unit EL870

The GL Sciences EL870 is an automated elution system designed to optimise one of the most critical steps in solid phase extraction (SPE). Elution directly impacts analytical precision, particularly in applications such as biological, food, and environmental testing for HPLC or GC analysis. By automating this process, the EL870 improves reproducibility, accuracy, and overall laboratory efficiency.

At the core of the system is a high-precision syringe pump that delivers controlled solvent flow, supported by a ‘Soak Mode’ function that pauses during elution to allow thorough solvent penetration of the SPE cartridge. This ensures stable recovery rates and consistent results. The EL870 accommodates both syringe barrel-type and Luer-type SPE cartridges, providing flexibility across different workflows. A straightforward keypad interface makes operation accessible to users of all experience levels, while its robust design enables reliable performance in applications including drinking water and environmental monitoring, aldehyde testing (atmospheric and in-vehicle), and food analysis.
