What is a Gas Chromatograph (GC) used for?

A Gas Chromatograph is an analytical instrument used to separate and analyse compounds that can be vaporised without decomposition. It is widely used for qualitative and quantitative analysis of volatile and semi-volatile organic compounds.

What is an FID and what are its advantages?

An FID (Flame Ionisation Detector) is a common detector for GC, highly sensitive to organic compounds. Its advantages include a wide linear range, high sensitivity, and robustness for many applications.

Can this unit be integrated with other laboratory equipment?

Yes, GC systems like the Varian 3900 can often be integrated with autosamplers, mass spectrometers (GC-MS), and data systems for enhanced automation and analytical capabilities. Compatibility should be confirmed with the seller.

What maintenance is typically required for a used GC system?

Typical maintenance for a used GC includes regular cleaning or replacement of consumables like liners, septa, columns, and detector jets. Calibration and system checks are also routine. The seller offers servicing/renovation/refurbishment at extra cost.

What are the common challenges when purchasing a used GC?

Common challenges include ensuring the system is fully functional, understanding its service history, and verifying the availability of spare parts and technical support. It is advisable to request a demonstration or detailed inspection.

This listing is for a Varian 3900 GC With FID and 1041 Packed Injector The Varian 3900 gas chromatograph (GC) is designed to meet the demands of the analytical laboratory with its compact design—GC occupies less than half the workspace of the average gas chromatograph unit. Models 39001-00 and -05 feature an icon-based keypad which simplifies training and increases daily productivity. Select one of six pre-programmed languages for further ease-of-use. Password protection locks keypad from unauthorized access. Each Varian 3900 GC unit features a front access column compact oven with Precise Temperture Control which uses standard 7" (17.5 cm) diameter capillary columns. Maximum operating temperature is 450°C—accommodates any application. Plus, the oven cools down from 450°C to 50°C in only 5.2 minutes! Dimensions and Weight Size: 21.8 in./55 cm (h) x12.5 in./32 cm (w) x 22 in./56 cm (d) Weight: 59 lbs/26.8 kg Equipment can be serviced/renovated/refurbished on request at extra cost.
