Introduction
The 700 Nano GC miniaturized gas chromatograph features a miniaturized design, concentrating all functional modules—including preprocessing, injection, flow control, separation, detection, computer, gas cylinders, and batteries—into a casing the size of just one A4 sheet of paper, weighing only 2.5 kg. The instrument supports up to two chromatographic analysis channels and supports various detectors such as FID, TCD, and PID. Simple operation and easy mobility, quick connection of carrier gas, sample gas, and power supply, suitable for specialized analytical scenarios with high volume and weight requirements. It can be widely applied in scientific research, petrochemicals, natural gas, power testing, environmental monitoring, coal mine safety, and process control.
The 700 Nano GC miniature gas chromatograph is available in three versions: standard, smart, and portable. The standard and smart versions are suitable for laboratory and online settings, while the portable version comes with a built-in miniature gas cylinder and battery, allowing it to be moved and operated continuously anytime, anywhere, making it ideal for on-site analysis.

Instrument features
The compact size and lightweight
Design greatly reduce the size and weight of the chromatograph, saving more space.
Multiple instruments array
Each operating independently, with analysis time generally only a few tens of seconds to a few minutes, and can be networked in parallel for synchronized operation.
Multi-detector
Supports FID, TCD, and PID detectors.
High sensitivity
FID detectors have a minimum detection limit of 0.05 ppm, and TCD detectors have a minimum detection limit of 0.5 ppm, which is dozens of times more sensitive than traditional gas chromatographs.
Low gas consumption
Only a small amount of sample gas is needed for analysis, and carrier gas flow rates are generally less than 5 ml/min, resulting in very low consumption.
Easy to maintain
Standardized pneumatic circuits and electrical interfaces are very convenient to connect, and even beginners can complete instrument maintenance within minutes after simple training.
Mobile testing
Quickly relocates testing sites, improving testing efficiency while reducing errors caused by sample circulation.
