Web Information

The Varian 3900 occupies less than half the workspace of many gas chromatograph (GC) units. Simple to use syringe trigger mechanism starts the GC upon injection. Electronic flow control of detector and injector eliminates knobs to turn off, thus saving you time, increasing long term precision of the GC.

The 3900 GC is an easy-to-use, high-throughput GC designed to meet the requirements of the routine analytical laboratory. It is a single channel, fixed configuration GC incorporating the same outstanding electronic flow control (EFC), injector, detector and autosampler as the full-featured Varian CP-3800 GC.

Small footprint (12.5inch/32 cm) saves precious bench space
Intuitive, icon-based keypad simplified operation
Compact and efficient Column Oven uses standard 7 in./17.5 cm diameter capillary columns, heats fast and cools down from 450°C to 50°C in only 5.2 minutes!
Full EFC control of injectors and detectors.
Roll-back cover provides complete and easy access to both the injector and detector for routine maintenance.
Choice of the CP-1177 isothermal split/splitless injector or the 1041 on-column megabore/packed injector.
Choice of a gas sampling valve or a liquid sampling valve upstream of the liquid injector.
Choice of FID or TCD.
Choice of the complete line of Varian autosamplers.
It is fully functional as a standalone GC or controlled through the Varian Star Workstation or the Galaxie Chromatography Data System
