FOCUS GC

Full-sized GC performance

Specifically targeted for routine quality control and high productivity laboratories, the Thermo Scientific FOCUS GC is a compact, single-channel gas chromatograph. Conceived and built around the “core” hardware and unique features of the Thermo Scientific TRACE GC Ultra, the FOCUS GCTM incorporates new, best of breed electronics. The FOCUS GC is the reference for precision and accuracy of results, as well as a standard for durability in QA/QC and high throughput environments.

Thermo Scientific AI/AS 3000 II Autosampler

Combined with the 8-sample AI 3000 II Autoinjector or the 105-sample AS 3000 II Autosampler , the FOCUS GC is positioned in line with your laboratory’s throughput requirements at any moment in time, thus preserving scalability.

Thermo Scientific TriPlus Autosampler

For additional productivity and flexibility, the Thermo Scientific TriPlus Autosampler is the ideal solution, able to simultaneously automate two adjacent FOCUS GC gas chromatographs. Scalability is preserved, with capacities for up to 300 samples and multiple injection modes.

Compact Size

Small footprint for bench space optimization: 430 x 510 x 350 mm ( HxDxW )

Optimized User Interface

Allows simple control of the main functions of the GC while preventing access to the more critical parameters of the method from unauthorized personnel. In line with the requirements of QA/QC environments.

Automatic Column Characterization

Automatic measurement of the effective column’s resistance for exceptional column-to-column and instrument-to-instrument retention time reproducibility at no additional cost.

Wide Oven

Wide oven with front opening allows easy accessibility for straightforward installation of capillary columns mounted on standard diameter cages. Oven dimensions are 225 x 225 x 140 mm ( HxWxD )

Additional Instrument Control

Instrument start-up and real-time diagnosis, on-line help describing each parameter, logbook with deviation records, and local keyboard lock provide complete and safe system handling.

Leak Check

Automatic leak check function for rapid routine system control.
