Introduction
The 700 EX Nano GC gas chromatograph is specifically designed for industrial analysis, making it suitable for online or portable applications in explosion-proof industrial settings. The instrument
adopts a compact explosion-proof design, is compact and lightweight, and can continuously and accurately monitor component concentrations in sample fluids in applications such as natural gas, refining, chemicals, power, steel, and environmental applications.
The 700 EX Nano GC gas chromatograph can be installed directly on pipelines or walls, eliminating the need for expensive analysis booths; simple pretreatment of sample gases enables online analysis of various gas components.
Thanks to extremely low gas consumption, a 40L carrier cylinder can provide continuous use for the instrument for up to 7 years; With a minimum operating power of up to 6 W, it can be equipped with a solar power system, suitable for outdoor or grid-free scenarios.
Features
> Compact size, lightweight
> Short analysis time, improves production efficiency
> Can be built into multiple pressure regulators and flow selection valves
> Pipeline or wall mounting, can be installed outdoors
> Local interface sensing touch or gesture operation
> Very low carrier and sample gas consumption
> Extremely low power consumption
> Low procurement, installation, and maintenance costs
