The AGS-72 gas sampler is an automated device designed specifically for the analysis of non methane total hydrocarbons and other gas samples. Its core function is to achieve precise, efficient, and automated injection of gas samples, thereby improving the accuracy of analysis results and experimental efficiency. The following provides a detailed explanation from three dimensions: functional features, technological advantages, and application scenarios:

1、 Gas injector is the core function: precise control of the entire gas injection process

1. Quantitative ring injection technology

Accurate control of injection volume is achieved through a quantitative loop, with a default injection volume of 1.0ml, which can be customized according to experimental requirements.

Quantitative ring technology combined with inert materials such as stainless steel or PEEK avoids sample adsorption or contamination, ensuring injection repeatability<1.5%.

2. Automated operation process

Sample loading: After connecting the sampling bag, the instrument automatically evacuates and blows the pipeline to eliminate residual contamination.

Injection control: Users can set parameters such as sampling time, injection time, and injection frequency through the screen. The instrument accurately injects samples at the set flow rate without manual intervention throughout the process.

Pipeline cleaning: Automatically backwash and clean all pipelines every analysis interval to prevent cross contamination and ensure data reliability.

3. Compatibility and Scalability

It can be seamlessly integrated with any brand of gas chromatograph (GC) without the need to modify chromatography equipment, reducing user upgrade costs.

Support optional electronic pressure/flow (EPC/EPC) dual control, graphical touch screen control, dual channel sampling and other functions to meet complex experimental requirements.

2、 AGS-72 gas sampler is a technological advantage: high stability and intelligent design

1. High repeatability guarantee

By relying on quantitative ring technology, inert materials, cleaning technology, and a stable automated control system, the long-term stability of the injection volume can be achieved, with a relative standard deviation of ≤ 2% for parallel samples, significantly better than manual injection.

2. Corrosion resistance and adaptability

Configure a corrosion-resistant sampling pump that supports negative or zero pressure sampling, suitable for the collection and analysis of corrosive gas samples such as volatile organic compounds (VOCs) and non methane total hydrocarbons.

3. Intelligent software support

Equipped with PC based online software, achieving 24-hour unmanned operation and industrial process monitoring.

The database automatically records all operational information (such as injection time, volume, and frequency) to ensure data traceability.

The software supports automatic synchronization of injection data to the chromatographic workstation, intelligent peak integration, reduces manual intervention, and improves data processing efficiency.

3、 AGS-72 gas sampler is an application scenario that covers gas analysis needs in multiple fields

1. Environmental monitoring

Used for continuous monitoring of non methane total hydrocarbons and volatile organic compounds (VOCs) in the atmosphere, supporting environmental protection departments in real-time assessment of air quality and tracking of pollution sources.

2. Industrial process control

In industries such as chemical, petroleum, and pharmaceutical, monitoring the dynamic changes in gas composition during the production process, optimizing process parameters, and improving product quality.

3. Scientific research experiments

Provide high-precision gas injection solutions for universities and research institutes, supporting experimental research in fields such as materials science, environmental science, and chemical engineering.

4、 AGS-72 gas sampler is user value: dual benefits of improving efficiency and reducing costs

1. Efficiency improvement:

Automated operations reduce manual intervention, increase daily sample processing capacity by over 50%, and shorten experimental cycles.

Intelligent software simplifies data processing flow, avoids manual integration errors, and accelerates result output.

2.成本降低：

No need to modify existing chromatography equipment, reducing upgrade costs.

High repeatability reduces the number of repeated experiments, saving sample and reagent consumption.
