FOCUS GC Description

Thermal Conductivity Detector (TCD).

The TCD is a universal type detector. It is used in the analysis of permanent gases
and other compounds for which the FID is non-sensitive.

External Detectors

FOCUS GC may also operate with external detectors. An external detector is a
detector controlled by an external control module. The FOCUS GC only provides
the heating through the base body, the gas supply and the signal analog to digital
conversion for acquisition.

Instrument Automation

FOCUS GC contains several automated features for running the GC,
communicating with other analysis equipment, and interacting with a data system.
Autosampler Interface
The TriPlus, AI 3000/AS 3000, AS 2000 or HS 2000 autosampler can be
connected to the GC.

Data Systems Interface

Your FOCUS GC generates analog and digital data output when you perform
chromatographic analysis. A computer with a Thermo data system or a computing
integrator can be used to process the data from the GC.
