JQ-8 Channel Automatic Gas Sampler
Product Overview
The JQ-8 Channel Automatic Gas Sampler is a high-efficiency multi-channel automated gas injection system designed for batch gas sample analysis in environmental monitoring, petrochemical industries, and third-party testing laboratories.
It enables fully automated injection of up to 8 gas samples per cycle, significantly improving analytical efficiency while reducing manual operation errors. The system is fully compatible with Agilent chromatography workstations and can also integrate with other GC brands via a standard “Start” trigger signal, ensuring seamless automation in gas chromatography workflows.
With features such as inert silanized tubing, heated transfer lines, and built-in vacuum pump support, the JQ-8 ensures high sample integrity, excellent repeatability, and reliable performance for sensitive gas analysis applications.

Key Features
• Fully automated 8-channel gas sample injection system
• Compatible with Agilent GC systems and other chromatography platforms
• External “Start” signal enables synchronization with various GC instruments
• Software-controlled injection program for simple and efficient operation
• High stability with excellent repeatability and reproducibility
• Built-in diaphragm vacuum pump for reliable sample transfer
• Silanized inert gas pathways for corrosion resistance and low adsorption
• Heated transfer lines prevent condensation and sample loss
• Minimal maintenance requirements, easy to operate
• Core components designed for long service life and industrial durability
• Suitable for sensitive gases including sulfur-containing compounds

Working Principle
The JQ-8 Automatic Gas Sampler operates through a programmable multi-channel injection system:
• Gas samples are loaded into 8 independent sampling channels.
• The system uses an internal vacuum-assisted transfer mechanism to ensure stable sample intake.
• Heated and inert silanized tubing prevents condensation and adsorption of reactive gases.
• Upon receiving a Start signal from the GC system, the sampler sequentially injects each gas sample.
• Software controls timing, sequence, and injection volume for each channel.
• The system completes fully automated multi-sample injection cycles with high precision and repeatability.
This design ensures consistent gas delivery, reduced contamination risk, and high analytical accuracy.
