The reliable and compact GC-8A is Shimadzu's basic gas chromatograph model for dedicated applications. Economical and simple to use, the GC-8A supports a single detector, manual pressure or flow control, on column injection port(s), and analog output. Isothermal or single temperature ramp program models are available. The GC-8A is only 17.3 inches (43.9 cm) wide, yet its large oven facilitates simple column installation and maintenance.
Detectors available:
- FID (Flame Ionization Detector)
- TCD (Thermal Conductivity Detector)
- ECD (Electron Capture Detector)
- FPD (Flame Photometric Detector)
