Environmental

Environmental laboratories are often faced with the need to determine a variety of environmental contaminants from complex matrices. This often requires the need for labor intensive sample preparation prior to determination of the analytes of interest. Sample preparation is considered the most error-prone and time consuming step in the analytical process. Automation can help to reduce costly errors and sample turnaround times. This in turn reduces the laboratory’s overall costs. 

Gilson, Inc. offers a variety of automated solutions for the environmental laboratory – including liquid handling, solid phase extraction (SPE), post-extraction clean-up by SPE, gel permeation chromatography (GPC) clean-up, HPLC column or specialty clean-up columns.
