Introduction
The 700 Portable GC Portable Multichannel GC is based on the PHXTEC Portable GC Portable Multichannel GC platform, each channel is a stand-alone gas chromatograph for fast analysis, high accuracy, low gas consumption, and simple operation.
The instrument has built-in integrated multi-channel gas chromatography analysis channels, communication modules, single-board machines, main control display modules, hydrogen generators, air generators, carrier cylinders and batteries, and can use up to 2 built-in high-pressure gas cylinders as carrier gases, or built-in hydrogen generators as carrier/combustion gas sources.
The 700 Portable GC Portable Multichannel GC is easy to operate, requires no complex gas connections and method setup, takes up half the space of conventional GC, and can be used as a laboratory gas chromatograph with minimal carrier gas and power consumption, making it suitable for on-site portable analysis.
The system supports a variety of detectors such as TCD, FID, FPD, and PID, and can be widely used in petrochemical, power testing, natural gas exploration, environmental monitoring, scientific research, coal mine safety, and process control.


700 Portable GC Portable Dual-Channel Gas Chromatograph

700 Portable GC Portable 3-Channel Gas Chromatograph
Features
Small size, light weight
Compact design and the selection of micro components make the size and weight of the chromatograph greatly reduced, and more space-saving.
Modular design
Each chromatographic module is a stand-alone gas chromatograph, and the modular design is easy to maintain and expand.
Multi-channel parallel processing
Each channel runs independently, and the analysis time is generally only a few tens of seconds to a few minutes, and the parallel analysis efficiency is high.
Fully Independent Modules
The modules integrate all functional units of chromatography and operate completely independently without the need for an additional main control board.
Multi-detector
Supports TCD, FID, FPD, and PID detectors.
High sensitivity
The minimum detection limit is 0.05 ppm for the FID detector and 0.5 ppm for the TCD detector, which is dozens of times more sensitive than traditional gas chromatography detectors.
Low
Gas consumption Only a small amount of sample gas is required for analysis, and the carrier gas flow rate is less than 10 ml/min, and the consumption is minimal.
Easy to maintain
Standardized air circuits and electrical interfaces are very easy to maintain, and even novice can replace modules in minutes with simple training.

Miniaturized design GC module
Portable
Combined with our proven built-in gas and power supply highly integrated solutions, the 700 Portable GC can be quickly transferred to the field for testing, improving inspection efficiency and reducing errors in sample circulation.
