Global Analyser Solutions – Compact GC


Best portable 
technology product


The CompactGC4.0 from GAS stands out as the most versatile Compact GC on the market. When approaching gas analysis from a laboratory perspective, one would typically opt for a traditional "GC with valve-oven" due to its reliability. However, if you consider it through the lens of a process controller's "need-for-speed," the Compact GC becomes the clear favorite. For those seeking the best of both worlds, the new CompactGC4.0 is the ultimate choice.

Key Features for Catalysis Research:

  • Pre-concentrator capillary column detector sample
  • Focus areas include renewable energy, CO2 reduction, and catalysis
  • Analyzes hydrocarbons C1-C10 with a rapid 3-minute cycle time
  • Single channel and upto four channels possible all on one Compact GC.
  • Capable of detecting permanent gases, sulfur, aromatics, and oxygenates
  • Supports multiple detection methods: FID, TCD, PDD, PFPD, ePD, and MS
  • User-exchangeable columns for added flexibility
  • Programmable column oven with a compact 19” footprint
  • Designed for continuous 24/7 operation

Fast Results: The CompactGC4.0 delivers outcomes in mere seconds, with cycle time matching runtime, eliminating the need for additional flushing or conditioning. Isothermal and programmable column ovens can heat up to 500°C/min.
User-Friendly Design: The CompactGC4.0 is straightforward and easy to operate, with instrument control seamlessly integrated into Chromeleon or Openlab/EZChrom chromatography data systems.

Interchangeable Columns: Utilising readily available standard columns, users can replace them in minutes using finger-tight couplings. This feature enhances flexibility and reduces operational costs, accommodating capillary, wide-bore, and packed columns.

Versatile Capabilities: The CompactGC4.0 offers up to four independent analysis channels and supports a variety of detectors, including TCD, FID, PDD, PFPD, PID, PED, MS, and VUV LUMA. Additional options include:

  • Backflush functionality to protect the analysis column from high boiling components and decrease analysis time
  • Stream selection valves for analyzing multiple sample streams
  • Sampling from small volumes at low pressure by creating a vacuum in the sample path
  • 4-20 mA analogue outputs

Due to its standard 19” enclosure, multiple CompactGC units can be housed together with other analytical equipment or a dynamic calibrator unit.
This hybrid technology, in its 19” format, merges efficiency and reliability, ensuring quick results. Its robust construction makes it the most cost-effective compact-GC analysis solution available today. The CompactGC4.0 redefines gas analysis efficiency and precision with a user-friendly interface that simplifies operations for both experienced professionals and newcomers. Its advanced software integrates seamlessly into existing workflows, enhancing productivity without sacrificing quality.
Moreover, the CompactGC4.0 features modular detector options, allowing customizable configurations to meet your specific analytical requirements. Whether in high-stakes research or routine management, this adaptable analyser meets varying demands with ease.
