Detailed information
Title A novel front-end automation approach for sample introduction, cleanup and collection
Summary A novel front-end system is shown that is capable of automated sample injection, solid-phase extraction and extract collection in sealed vials. Analysis methodology can be easily selected by means of the touchscreen of the Xprezzo. The combination with a multipurpose autosampler for extract collection emphasizes the system potential. Both the LC and online SPE mode show good linearity and repeatability. For extract collection the system flow path is dried with air. A compromise is made between drying time and the residual liquid inside the flow path. For Carbamazepine on a C18HD cartridge an elution volume of 180 µL was found to be most suitable. A good overall performance is shown for the complete inject, extract and collect approach, i.e., no analyte loss and linearity / repeatability that can measure up with default LC analysis.
