His work is characterized by a focus on utilizing liquefied gases to improve analytical processes.

Latest Patents

Kaziunas holds a patent for a "Single phase high pressure liquefied gas chromatography system and method." This invention utilizes a mobile phase comprising liquefied compressible gas and miscible organic solvents. The system employs carbon dioxide (CO2) as the compressible fluid, which is tapped from an existing source and depressurized through a flow control metering station before solvent addition. The mobile phase flows through a sample vessel containing analytes and a chromatography column for sample separation. A back pressure regulator maintains a set elution pressure in the chromatography column, allowing CO2 to remain in liquid phase for elution, thus avoiding two-phase conditions that can adversely affect analyte resolution. The system operates at CO2 pressures of less than 100 bar and room temperature, eliminating the need for high-pressure pumps and chillers typically required in supercritical fluid chromatography.
