High Performance

In addition to its eco-friendly features, the GC-2025 inherits the High-Speed Scanning
functionality of Shimadzu’s high-end capillary gas
chromatograph, GC-2010 Plus, delivering superb performance Narrow-bore capillary columns reduce analysis time and improve
for capillary analysis. GC-2025 provides high-quality analytical production capacity. With its advanced flow controller
results and improved productivity. (maximum pressure: 970kPa, maximum flow rate: 1200mL/min),
the GC-2025 is suitable for high-speed analyses using
narrow-bore capillary columns.
