Virginia State University awarded contract PO05470805 to Metrohm USA on September 16, 2026, with a cumulative value of $14,609.83. The primary deliverable is a PGSTAT 204 modular potentiostat/galvanostat instrument designed for electrochemical analysis. This instrument features a compliance voltage of ±20 volts and a maximum current capacity of ±400 milliamperes, with potential accuracy of ±0.2 percent and current accuracy of ±0.2 percent. The system includes Universal Serial Bus connectivity and operates with NOVA 2.x control software, enabling electrochemical impedance spectroscopy measurements through the FRA32M module with a frequency range of 10 millihertz to 32 megahertz and integrated data analysis capabilities including fit simulation and graphical equivalent circuit modeling.

Supporting the primary instrument, Metrohm USA will deliver complementary electrochemical testing components valued at $1,662.44, including glassy carbon substrates (10 millimeter by 10 millimeter by 1 millimeter), a basic sample holder with nickel contact, platinum sheet electrodes with approximately one square centimeter surface area, and a silver/silver chloride reference electrode without organic components. All deliverables are directed to Tiron Jahinge at Virginia State University. The contract represents a complete electrochemical analysis system supporting research or analytical applications within the institution.
