The German standard DIN 38 407-41 describes a method for the analysis of volatile compounds from aqueous samples by headspace-solid-phase microextraction (HS-SPME). Analytes are volatile, organic compounds (VOCs), fuel constituents (BTEX) and methyl-tert.-butylether (MTBE). The method allows for the detection of such contaminants in drinking-, ground- and surface waters by gas chromatography coupled to mass spectrometry (GC-MS). With the small sample vol¬umes of 10 mL, the working range of the original method is 0.01 to 100 μg/L, with the lowest reported detection limits being in the range of approx. 10 ng/L.
PAL SPME Arrow is a suitable tool for fulfillment of the German standard method DIN 38 407-41 for head¬space-solid-phase microextraction of volatile analytes from aqueous samples. Obtained detection limits with the novel device are at least one order of magnitude better than the values that were reported for the classical SPME fiber. Meth¬od repeatability and linearity are on par for both techniques. In addition, the improved mechanical reliability of PAL SPME Arrow can be expected to benefit the overall method stability over prolonged, automated measurement series.
A New Tool for the Automated Sample Preparation of Whole Blood Samples by LC-MS using a Commercial AutosamplerPoster
Automated sample preparation reduces the costs per sample and minimizes sample handling errors. Usually expensive and highly specialized pipetting robots are used. However, most of these systems are not designed with a direct interface for LC-MS applications. In addition common pipetting systems are not optimized for smaller scale sample series. Here we present a new tool for liquid handling of whole blood samples and direct sample injection.READ MORE
