Conventional solid phase extraction (SPE), an essential step in many analytical procedures, includes a number of laborious steps. With the help of the modified parallel evaporator, Syncore® fromBuchi (Switzerland), all essential work-up steps including evaporation of the eluates are achieved without any sample handling between the individual steps.
Conditioning of the SPE cartridges, enrichment of the samples, washing
elution of the target substances and evaporation or concentration to a defined residual volume can be carried out without interruption on one single instrument.
This eliminates the risk of cross contamination and results in high recovery rates and in a high sample throughput.
Up to 12 samples can be carried out in parallel whereas the flow of each sample can be controlled individually achieving a safe operation and high recovery rates. The liquid which passes the SPE cartridge can either be collected in a waste vessel or in a collecting vessel. The eluate is then evaporated to dryness or to a pre-defined residual volume while the evaporated solvent is condensed and collected in an environmentally sounded way.
