  • Testing of numerical advection schemes and splitting techniques used in pollution dispersion modelling on an analytic solution

    In the real nature the processes of pollutants advection, their release in and removal from the atmosphere take place simultaneously. In dispersion modelling, these processes are considered separately, one after another within a time step, which causes the generation of some specific errors. Two types of numerical advection schemes, typical Eulerian and semi-Lagrangian one, are considered. The ...

  • When Consumables Kits are Greater Than the Sum of their Parts

    ProteinWorks and GlycoWorks kits address more than sample prep challenges One of the most challenging parts of an LC-MS workflow happens before analytical chemists even turn to their instrument: Sample preparation. Get it right, and the analytical run performs as expected. Get it wrong, and the assay has any number of problems, from poor sensitivity to poor reproducibility. The ...

  • Interpretation of total petroleum hydrocarbon (TPH) results with RaPID assay kits

    SUMMARY The SDI RaPID Assays for petroleum hydrocarbon fuels (Total BTEX, PAHs) have been shown to provide excellent correlation with GC based (8015M) and IR based (418.1) methodologies for testing Total Petroleum Hydrocarbons (TPH). Linear relationships between immunoassay and TPH results with both gasoline and diesel fuels are demonstrated. Fuel reactivities with immunoassay are shown to ...
