Latest Patents
Davis holds a patent for an "Atmospheric pressure, glow discharge, optical emission source for the direct sampling of liquid media." This device operates at atmospheric pressure and utilizes a glow discharge spectroscopy (GDS) source. One of the discharge electrodes is formed by an electrolytic solution containing the analyte specimen. The passage of electrical current across the solution/gas phase interface causes local heating and volatilization of the analyte species. The resulting optical emission and ionization allow for the identification and quantification of analyte elements through optical emission spectroscopy (OES) or mass spectrometry (MS). The device can use the analyte solution as either the cathode or anode, with operating parameters depending on the electrolyte concentration and the gap between the solution surface and the counter electrode. Typical conditions include discharge currents of about 10 to 60 mA and potentials of about 200 to 1000 volts. Electrolyte solutions with pH, pNa, or pLi values of about 0.5 to 2 and interelectrode gaps of about 0.5 to 3 mm produce stable plasmas, allowing for flow rates of up to about 2.0 mL/min.
