Title Hyphenation and automation of large-volume online-SPE with liquid chromatography mass spectrometry
Summary Solid Phase Extraction (SPE) is a technique usually required to achieve an acceptable limit of detection for target analysis in environmental samples. A severe drawback of offline SPE is the time consuming sample preparation. Online SPE circumvents this and enables complete automating of the SPE-LC-MS/MS workflow. Innovative software algorithms help to perform SPE in parallel and can thus reduce the overall cycle time for sample preparation and analysis. For the highest degree of flexibility, the new autosampler platform in combination with an automated cartridge exchanger was used. Therefore, the injection volume can be varied from 10 µL up to 10 mL.

Remarks For sample enrichment C18 phase is not suitable for polar and moderately polar analytes. • Polymeric materials like Resin SH and GP very suitable for enrichment of polar and non polar analytes. • In order to obtain small peak widths small particle packed SPE cartridges (< 5 µm) are preferred. cartridges • Innovative software algorithm (Chronos) is a useful tool for interlacing and automation of complete workflow.
