Varian 3900 GC: Reliable and Simplified Analytical Performance
The Varian 3900 GC is a single-channel gas chromatograph designed to offer a streamlined user experience and easy maintenance, while maintaining the precision required for laboratory analyses. Engineered to meet the demands of routine and quality control applications, this system stands out for its flexible configuration and stable operation.
It can be equipped with either a CP-1177 split/splitless injector or a 1041 on-column injector, and with either an FID (Flame Ionization Detector) or a TCD (Thermal Conductivity Detector). This modular design allows the system to adapt to various chromatographic applications. The programmable column oven, with a maximum temperature of 450 °C, enables multiple ramp-and-hold programs for effective thermal separation of compounds.
The 3900 GC can be operated with or without a keypad. In the keyboardless version, it is fully controlled via Star or Saturn Workstation software through direct Ethernet connection, allowing for seamless integration into laboratory networks. A cycle time extension function offers increased flexibility during analyses.
Its interface features color-coded keys to distinguish functions (edit, action, view), with smooth navigation supported by scroll buttons. The system supports only one active mode at a time, with the ability to edit methods during runs without affecting the current sequence.
Maintenance is optimized to ensure long-term reliability: easy replacement of septa, injector liners, gas filters, FID jets, and more. Since carrier gas purity is critical, the use of a CP-Gas Clean purification kit is recommended.
As an option, the system can be fitted with a liquid CO₂ cryogenic cooling module for the oven, as well as a CP-8400 or CP-8410 autosampler mounted directly on the top cover.
This model is highly regarded for its reliable performance, straightforward network connectivity, and intuitive handling—making it a robust solution for laboratories seeking a powerful yet easy-to-use gas chromatography system.
