Abstract: A liquid sampling, atmospheric pressure, glow discharge (LS-APGD) device as well as systems that incorporate the device and methods for using the device and systems are described. The LS-APGD includes a hollow capillary for delivering an electrolyte solution to a glow discharge space. The device also includes a counter electrode in the form of a second hollow capillary that can deliver the analyte into the glow discharge space. A voltage across the electrolyte solution and the counter electrode creates the microplasma within the glow discharge space that interacts with the analyte to move it to a higher energy state (vaporization, excitation, and/or ionization of the analyte).

Abstract: A system, apparatus and method matches sales leads to purchases by receiving product inventory data, normalizing the received product inventory data, and storing the normalized product inventory data a database. A product availability query is received that includes a requested product and a location. Search results are obtained by searching the database for normalized product inventory data that best matches the requested product and the location. The search results are provided to the potential customer, and the product availability query and the search results are stored in the database. Product sales data is received from the vendor, and the received product sales data is stored in the database. A determination is then made whether a product sale resulted from the product availability query by calculating a match score based on the stored product sales data, the stored product availability queries and the stored search results.
