Place of performance is the USGS facility at 12201 Sunrise Valley Drive, Reston, Virginia (MS-153). The TGA must be a stand-alone, fully integrated system with installed dimensions not exceeding 21" W × 25" D × 25" H and weight limited to 100 lbs. The system must include a robotic autosampler for high-throughput analysis, a water bath cooling system, and a gas controller operating at 1–3 bar pressure with software tunability supporting air, argon, carbon dioxide, nitrogen, oxygen, and helium at 3 ml/min flow rate tolerance. The furnace must heat to at least 1100°C with 0.5°C temperature precision and accommodate maximum heating rates of at least 250°C/min, with a minimum furnace diameter of 20 mm and volume of 45 mL, including built-in cooling jacket and cell thermocouple. The system must include expansion options for peripheral gas analysis devices and demonstrate capability to analyze geological samples including coals, carbonates, and clay. Power supply must be factory-set for 115V or 230V operation. Vendors must provide initial user training, EQPac Comprehensive Qualification services, and available annual service plans.

The procurement includes thermal analysis system, cooling system mini chiller, dryer gas, perpetual software license, crucibles (various sizes), shipping, and handling.
